Abstract

Purpose

The study attempts to develop a multi-product multi-period (MPMP) aggregate production plan (APP) to fulfill the customers' demand in terms of throughput and lead time for achieving market competence.

Design/methodology/approach

This research proposes an integrated Fuzzy analytical hierarchy process (FAHP), multi-objective linear programming (MOLP), and simulation approach. Initially, FAHP is used to select the essential objectives a firm desires to achieve. Adopting the MOLP, an APP is formulated for the firm under study. Later, the simulation model of a firm is created in a discrete-event simulation (DES) software Arena© to evaluate the applicability of the proposed APP. A comparative analysis of the manufacturing performance levels (namely throughput, lead time, and resource utilization) achieved through the implication of an existing production plan and proposed APP is conducted further.

Findings

The findings from the study depict that the proposed MOLP-based APP can satisfy the customers' requirement (namely throughput and lead time) and improve the level of resource utilization compared with the firm's existing production plan.

Research limitations/implications

The proposed research facilitates researchers and practitioners to understand the process of developing MOLP-based MPMP APP and analyzing its applicability through simulation technique to be utilized for developing APP at their firm.

Originality/value

An integrated FAHP-MOLP-simulation framework is the novel contribution to the literature on production planning. It can be extended to solve strategic, tactical, and operational problems in different domains like service, healthcare, supply chain, logistics, and project management.

Abstract

MR. F. W. F. ARNAUD, the Public Analyst for the Borough of Portsmouth, delivered a lecture on this subject at the Town Hall on April 27. The lecturer commenced his address by stating that many of the objections to the use of certain preservatives which he might have occasion to put forward were not necessarily his own individual objections, but were the objections of many scientific men who had dealt with all sides of this difficult subject. There was a tendency on the part of some people to regard preservatives as disinfectants, but disinfectants and antiseptics were two different things. A disinfectant not only retarded the growth of microbes, but actually killed them, while an antiseptic preservative merely retarded their growth or formation. Two common antiseptics were sugar and salt. It had been contended that a small dose of a chemical preservative was preferable to a dose of microbes. The effect of a preservative was not to kill the life already present, but to prevent the free multiplication of the organisms present, and the swallowing of a dose of preservative did not necessarily prevent the swallowing of a dose of microbes. There were many old forms of preserving food, such as the use of sugar for fruit and condensed milk; of vinegar for vegetables; and the process of smoking for bacon and fish, smoke being very destructive to microbes; but the oldest form of preservation was the process of salting meat and fish. Another form of preservation was the method of preventing the access of air to perishable articles, as in the cases of eggs and lard. Then there was drying, as in the case of fruit, and chilling, or freezing, as in the cases of meat, milk, poultry, and fish. The temperatures employed for freezing food varied considerably, and depended chiefly upon the length of time during which storage was necessary. If it were only desired to keep meat for a week or two, a low temperature was not necessary, but one of 40 deg. F. was sufficient. Any cooling process was equivalent to the use of a great deal of chemical preservative. A cooling to 50 deg. P. was equivalent to the addition of boric acid to the extent of .05 per cent. At a normal summer temperature of 70 deg. P., two microbes would produce 62,100 in the course of twenty‐four hours; hence the necessity for cooling articles of food. The drawback to most of these methods of preservation was that sugar, salt, and cold were not applicable in every case. Exclusion of air and subsequent sterilisation had their drawbacks also. When sterilisation was complete and the air was exhausted, no putrefaction could take place, and the food should remain indefinitely unchanged. In the matter of tinned meat, the drawback lay chiefly in the failure to ensure complete sterilisation, and in the dissolving of tin, and occasionally lead, from the metal enclosing the food. In the case of tinned meat putrefaction to any considerable extent could be easily recognised by the blown condition of the tin and an absence of the inrush of air when the tin was pierced. Such food was a source of great danger, and if eaten the meat was liable to give rise to ptomaine poisoning—which was occasioned by eating the poisonous products produced by various bacteria. The danger of metallic poisoning could be largely overcome by the use of glass or earthenware vessels. Preservatives in use at the present time were: Benzoates, fluorides, formalin, salicylic acid, sulphites, saccharin, and beta naphthol, generally used singly, though there were some very complicated preservatives on the market. With reference to the use of salt and sugar as preservatives, little or nothing could be said against their use, for sugar was in itself a food and had a well‐known food value. Salt, too, was an essential constituent of our food, for without the elements of which it was composed we could not exist. Naturally, the assimilation of a large quantity of salt was not desirable, but it could not be urged, as, for instance, in the case of boric acid, that it was a substance foreign to the constituents of the human organism, for it was indispensable. Boric acid, however, played no part in any of the essential life processes.

Abstract

Purpose

The purpose of this paper is to demonstrate the application of vendor rationalization strategy for streamlining the supplies and manufacturing cycle time reduction in an Indian engineer-to-order (ETO) company. ETO firms are known for a large number of vendors, co-ordination hassles, rework problems and its impact on cycle time and operational excellence.

Design/methodology/approach

The research demonstrates the case-based application of Kraljic’s matrix for supply and leverages items, on-the-job observations, field visits, discussions and analysis of supplies reports.

Findings

The study guides on the rationalization of supplies and the necessary strategic alignments that can significantly reduce supply risk, costs, manufacturing and delivery cycle time along with co-ordination hassles. The study depicts the challenges of ETO environment with respect to supplies, and demonstrates the effectiveness of vendor rationalization application for the case company and weaknesses of commonly practiced vendor management approaches.

Practical implications

To be competitive, companies should rationalize supply items and vendors based on the nature of items and their subsequent usage by applying Kraljic’s matrix-based classification. The immediate implication of vendor rationalization is misunderstood as reducing supply base, but it does much more and includes review of supplies, nature of items and strategic alignments, leading to win-win situation for company and suppliers.

Originality/value

For the rationalization of supplies, while procuring and dealing with vendors, executives should envisage engineering nature of components, considering cross-functional requirements and integration of components in context to ETO products/projects environments. There is a dearth of studies focusing on vendor rationalization aspects in ETO setups in fast-developing country context.

Abstract

THE enterprise of two London newspapers, the Tribune (for the second time) and the Daily Chronicle, in organizing exhibitions of books affords a convenient excuse for once again bringing forward proposals for a more permanent exhibition. On many occasions during the past twenty years the writer has made suggestions for the establishment of a central book bazaar, to which every kind of book‐buyer could resort in order to see and handle the latest literature on every subject. An experiment on wrong lines was made by the Library Bureau about fifteen years ago, but here, as in the exhibitions above mentioned, the arrangement was radically bad. Visiting the Daily Chronicle show in company with other librarians, and taking careful note of the planning, one was struck by the inutility of having the books arranged by publishers and not by subjects. Not one visitor in a hundred cares twopence whether books on electricity, biography, history, travel, or even fairy tales, are issued by Longmans, Heinemann, Macmillan, Dent or any other firm. What everyone wants to see is all the recent and latest books on definite subjects collected together in one place. The arrangements at the Chronicle and Tribune shows are just a jumble of old and new books placed in show‐cases by publishers' names, similar to the abortive exhibition held years ago in Bloomsbury Street. What the book‐buyer wants is not a miscellaneous assemblage of books of all periods, from 1877 to date, arranged in an artistic show‐case and placed in charge of a polite youth who only knows his own books—and not too much about them—but a properly classified and arranged collection of the newest books only, which could be expounded by a few experts versed in literature and bibliography. What is the use of salesmen in an exhibition where books are not sold outright? If these exhibitions were strictly limited to the newest books only, there would be much less need for salesmen to be retained as amateur detectives. Another decided blemish on such an exhibition is the absence of a general catalogue. Imagine any exhibition on business lines in which visitors are expected to cart away a load of catalogues issued separately by the various exhibitors and all on entirely different plans of arrangement! The British publisher in nearly everything he does is one of the most hopeless Conservatives in existence. He will not try anything which has not been done by his grandfather or someone even more remote, so that publishing methods remain crystallized almost on eighteenth century lines. The proposal about to be made is perhaps far too revolutionary for the careful consideration of present‐day publishers, but it is made in the sincere hope that it may one day be realized. It has been made before without any definite details, but its general lines have been discussed among librarians for years past.

Abstract

Purpose

ETO supply chains produce high-value products on a project basis. The occurrence of delays is a major problem that impacts the performance of a company and its supply chain. The purpose of this paper is to analyze the cause of delays and to understand the role of coordination to mitigate them.

Design/methodology/approach

An in-depth case study was conducted to identify problems that delay a project and to examine such problems from a systemic perspective. Based on data from interviews, group meetings, field observations and documentation, a pattern is proposed to explain the relation between coordination and lead time.

Findings

Conceptually, to reduce the project lead time a higher level of concurrency is necessary. However, more concurrency increases the interdependencies between activities, something which demands more coordination effort. Since the coordination mechanisms applied are not appropriate to cope with the increasing coordination effort, a number of problems appear causing reworks and delays which increase the lead time.

Research limitations/implications

The main limitation is that the authors are not able to distinguish which particular project characteristic influences the adoption of a specific coordination mechanism. Further research is required to examine the effect of various coordination mechanisms across a higher number of projects.

Practical implications

Practitioners can benefit from discussions in this study to comprehend how coordination can improve the delivery performance in ETO supply chains.

Originality/value

This study contributes to a better understanding of coordination in ETO supply chains by making sense of problems that delay the project. Matching the coordination mechanisms with the required coordination effort, which is based on the project characteristics, is a way to avoid delays and reduce the lead time.

Abstract

Purpose

The process of predicting construction costs and forecasting price fluctuations is a significant and challenging undertaking for project managers. This study aims to develop a construction cost index (CCI) for Jordan’s construction industry using fuzzy analytic hierarchy process (FAHP) and predict future CCI values using traditional and machine learning (ML) techniques.

Design/methodology/approach

The most influential cost items were selected by conducting a literature review and confirmatory expert interviews. The cost items’ weights were calculated using FAHP to develop the CCI formula.

Findings

The results showed that the random forest model had the lowest mean absolute percentage error (MAPE) of 1.09%, followed by Extreme Gradient Boosting and K-nearest neighbours with MAPEs of 1.41% and 1.46%, respectively.

Originality/value

The novelty of this study lies within the use of FAHP to address the ambiguity of the impact of various cost items on CCI. The developed CCI equation and ML models are expected to significantly benefit construction managers, investors and policymakers in making informed decisions by enhancing their understanding of cost trends in the construction industry.

Abstract

Purpose

Homebuyers' motivation to purchase the green building (GB) is vital for the widespread adoption of greener practices and for tackling the adverse impact of the built environment. In this regard, through the lenses of qualified and competent GB developers (GBD) and real estate agents (REAs) using judgment sampling technique, this paper aims to evaluate the factors stimulating the purchase intention of Malaysian homebuyers.

Design/methodology/approach

The study uses the interval-valued fuzzy Delphi method (IVFDM) to identify influential factors, while the cybernetic fuzzy analytic hierarchy process (CFAHP) for prioritizing the identified factors according to their significance in nationwide promotion of GBs is utilized.

Findings

The findings, which are consistent with those reported in the literature and validated by the focus group, uncover the most prominent factors that drive the purchase intention of GB homebuyers. The results indicate that the homebuyers are familiar with the benefits of GB; however, the benefits are not sufficient to overcome the perceived “high cost” of green practices. Hence, homebuyers still seek financial incentives, which is a clear indication that financial issues are the most motivating factor.

Practical implications

Increase in informative promotion of GB is necessary, particularly among prospective homebuyers in developing countries where GB adoption is in its infancy. Frontline players (those who are responsible for wider promotion) can utilize the factors that this study found to be important to identify appropriate steps to increase prospective homebuyers' motivation for purchasing greener dwellings.

Originality/value

The contribution of this paper is threefold. First, review and identification of the most cited determinants that have been reported in the context of the subject. Second, this paper presents the most significant determinants in a developing country setting through the lenses of Malaysian experts in the area. Third, improvement measures could be implemented in Malaysia and other developing countries to promote the GB paradigm with an aim to make the building environment more sustainable.

Abstract

Population ageing, coupled with economic uncertainty and a shifting workforce structure, has directed the attention of public and organizational policy makers toward the potential contribution of older workers and skilled migrants in meeting labor supply shortages in ageing populations. This chapter presents labor supply and demand scenarios for 10 OECD countries and examines trends in the labor force participation of older workers against the backdrop of changes to the nature of work in an era of globalization, casualization, and, increasingly, automation. Brief analysis of each country’s situation and policy responses indicates that China, Japan, and Korea stand out as being at particular risk of being unable to maintain growth without undertaking drastic action, although their areas of focus need to differ. A limitation of the study is that GDP projections used in labor demand analysis were based on historical rates and represented past potential and a long-run average of historic economic output. Future research might also undertake comparative analysis of case studies addressing different potential solutions to workforce ageing. A key implication of the study is that there is a need to take a blended approach to public policy regarding older workers in a changing labor market. Where migration has historically been a source of labor supplementation, this may become a less viable avenue over the near future. Future shortfalls in labor imply that economies will increasingly need to diversify their sources of workers in order to maintain economic growth. For public policy makers the challenge will be to overcome public antipathy to migration and longer working lives.

Abstract

Purpose

Considering the human factor, the quality of the personnel is vital to ensure especially the value creation in the ports. Therefore, employee quality stands out for withstanding the pressures that stem from global trade on its operational speed felt by ports in recent years. Accordingly, the selection of the qualified personnel at the ports is very critical and a tool based on dynamic capabilities is needed to manage this process well. The aim of this study is to develop a model based on dynamic capabilities for recruitment process of ports.

Design/methodology/approach

Port personnel should have dynamic capabilities detected from the literature. These capabilities were approached as criteria. In this study, Buckley's proposed fuzzy analytical hierarchy process (AHP) method was employed for weighting the whole criteria. After that, weights of the criteria were used to prioritize alternatives with the fuzzy TOPSIS method.

Findings

This model reflects port managers' priorities and port customers' evaluations. Thus, the model can also reflect the level of integration of ports' related department managers into the recruitment process. The analyses allow the evaluation of the attitudes of the human resources department in the related port while fulfilling the personnel recruitment function. As a result of analyses, differences between perceptions of port managers and customers served as a feedback to the human resource management department of the ports.

Originality/value

One of the originalities of this study was derived from its customer-oriented perspective. This is a unique study that gathers common personnel capabilities related to the operation, planning and customer relationship departments and evaluates the success of these capabilities from the customer perspective.
