Abstract

Purpose

The main objective in writing this paper and conducting this research is to enhance the productivity in manufacturing operations by making them cost effective.

Design/methodology/approach

This paper presents a target‐costing system and model developed for the turning operation and it has a user interface designed in Microsoft Visual Basic® with a database developed by using Microsoft Access®. An algorithm is developed to apply the concepts of target‐costing that selects the machining parameters and then determines the machining cost. A geometric programming model (Gopalakrishnan and Al‐Khayyal) was used in the development of this system.

Findings

The research determined that target‐costing models can be developed for the manufacturing industry and can be implemented in realistic manufacturing environment. The research also showcased the utility of the target‐costing model in terms of the underlying detailed system level parameters.

Research limitations/implications

The research focuses on one manufacturing process but can be extended to other manufacturing processes and business cost and profit centers for providing overall and enhanced benefits at the corporate levels.

Practical implications

The research details the development of a model that has been validated using practical shop floor data, hence implying its application in a wide variety of situations.

Originality/value

The original value of the paper lies in identifying the critical parameters and modeling approach towards target‐costing.

Abstract

A plant layout in the context of manufacturing facilities design consists of the production areas, manufacturing support areas and personnel areas. In facilities design, plant layout has been determined to be one of the most important elements in the effectiveness of systematic manufacturing operability. This paper describes the development of a split departmental plant layout generation system (LAYSPLIT) in the domain of facilities design to develop layouts that will minimize the material handling costs. The plant layout generation system consists of a data acquisition module, a pair‐wise departmental exchange module, a layout development module, and a graphical representation module. The approach used to develop the system using a split departmental method, and the characteristics of the system are outlined. The advantages of the developed system in terms of facilitating effective operations and increasing productivity in manufacturing environments are discussed. The results obtained from LAYSPLIT are compared with that produced by the MCRAFT system and discussed.

Abstract

Purpose

This paper seeks to apply a heuristic approach to solve the facility layout problem and the description of a new computer‐aided layout design system.

Design/methodology/approach

The system utilizes a new approach for computing the adjacency scores, stacking of departments, and reserving or changing the department's shapes and dimensions. The system algorithms are based on calculating the minimal distance between departments and modified departmental closeness rating.

Findings

The research addressed in this paper has resulted in developing FLASP (Facility LAyout Support Program) software. FLASP could reduce the number of iterations needed to reach the optimal solution of the layout problems by restricting the location for each department depending on the relationships between them.

Practical implications

The system is built on a set of algorithms that are concerned with stacking, calculating the shortest rectilinear distances between departments, adjacency matrix system, modifications capabilities, and plans main aisles surrounding each department.

Originality/value

The program gathers the importance of both the adjacency relationships and the distances between departments in a way that depends on the concept that the adjacency score should not be nullified just because the two departments are no longer strictly adjacent. It rather considers that the adjacency score fades away gradually with the increase of distance between the two departments which leads to a main difference in distance consideration.

Abstract

This paper describes the design and development of a system for the selection and construction of vertical and horizontal machining center packages with a base machine and options format subject to budgetary constraints. Options are categorized and divided into groups depending on their utilization, and their selection is based on a priority setting. Options are categorized as those providing the capability for high speed, enhanced levels of productivity, high levels of machining complexity, high levels of machining accuracy, and potential for the inclusion of automation to facilitate and satisfy production requirements. A user‐friendly and object‐oriented computer0based decision support software system was developed incorporating real data from a machine tool sales organization.

Abstract

Purpose

The purpose of this paper is to explore the interface between Lean strategy and organisational transformation by scrutinising the literature on why Lean strategies fail to be implemented and/or sustained.

Design/methodology/approach

As a conceptual and research paper, it develops a hypothesis. It encompasses philosophical discussions and comparative studies of others’ work and Lean thinking alongside its links to the principles, ideology, philosophy and underpinning values. The search involved a total of 1,931 articles spanning across 75 different journals. The content analysis approach suggested by Mayring (2004) was selected.

Findings

Successfully implementing Lean is more complex than often recognized within the literature, and the alignment between strategy and organisational transformation is repeatedly not undertaken. The investigation indicates policymakers need to view Lean as an ideology and not simply another process.

Research limitations/implications

This paper addresses the inaccurate representation in the concept of Lean as a strategy. While a major evolution has occurred comprising the inputs perceived as imperative for Lean success, a translucent empathy of its philosophy alongside an acknowledgement of the magnitude of the change and transformation necessary has been comparatively perplexing. This paper has implications for academic scholars of strategy and organisational change, as well as for practitioners seeking to implement organisational change.

Originality/value

Empirical evidence suggests that most Lean strategies struggle. Customers are becoming more demanding, markets are becoming more customised, and product life-cycles getting shorter are dictating that Lean needs to be embraced as an ideology.

Abstract

Purpose

Multitasking machining (MTM) systems have become increasingly sophisticated and expensive capital equipment. The lack of practical guidelines for selection of these machines can lead to significant undesirable machine attributes, application mismatch, and longer return on investment. The purpose of this paper is to provide an insight to numerous features and configurations of MTM systems and to present several application‐based selection guidelines.

Design/methodology/approach

A taxonomy of MTM systems is developed based on the number of axes of motions, tooling and spindle systems. Practical guidelines for general and advance features are presented with special regard to multi‐axis and multi‐spindle features.

Findings

MTM systems are capable of meeting several production goals such as cycle time reduction, minimizing non‐value added times and concurrent processing of multiple parts. However, they possess inherent programming challenges due to their complex configuration and simultaneous machining functions.

Research limitations/implications

The diversity of system configurations demand a decision support system, such as a rule‐based expert system to capture the many variations of MTM systems.

Originality/value

This paper should be useful to decision makers in industry or academia who are involved in selection of MTM systems.

Abstract

Computer‐based models for the automatic generation of facility layouts have been shown to provide significant benefits to the industrial community for the planning and development of facilities. In a manufacturing environment, layouts are often needed for the manufacture, storage and shipment of specific product types within specific time periods. This is especially true in metal fabrication plants, as the dynamic nature of product storage and manufacture dictates the need for effective layout generation to achieve cost reductions. The system described in this paper integrates raw material storage, inventory management, scheduling and rack system design with facility layout development for the most satisfactory dynamic response. The research addressed in this paper has resulted in the development of a computer‐based model that focuses on the concept of integrating the domains of plant layout, material handling and warehousing in terms of raising overall effectiveness.

Abstract

Purpose

The purpose of this paper is to contribute to the diffusion of facilities management (FM) as a sustainable tool to facility performance within the perspective of public universities in Nigeria.

Design/methodology/approach

A review of the literature reveals the practices of FM in both the educational and institutional buildings. Factors influencing the practices and strategies for sustaining facilities condition were evaluated. Data were collected through a well-structured questionnaire administered on both the technical and managerial officers in charge of FM in Nigeria public universities. Data collected were subjected to both the descriptive and inferential statistical tools.

Findings

The FM practice in the Nigeria public universities is found to be lagging behind private sector experience, despite the significant benefits of FM to learning process. In particular, passive actions are being taken to manage facilities, even when most are obsolete and deteriorated. Critical challenges to FM practice are low level of technology, poor funding and poor policy implementation. Outsourcing of technical personnel is essential to ameliorate the conditions of public universities’ facilities in Nigeria.

Practical implications

This paper helps policymakers and administrators to know the condition of facilities and understand the FM practice in the Nigerian public universities.

Originality/value

Reactive/passive practice is the norm in FM of public universities in Nigeria. However, outsourcing of technical personnel in FM has a great potential for functional facilities in public universities.

Abstract

Purpose

Amidst the backdrop of a wide array of structural developments that have revolutionized the competitive landscape of Indian commercial banking, this paper aims to empirically examine the role of two external monitoring mechanisms – competition and concentration on financial stability and further highlights the significance of bank-level heterogeneity in the nexus.

Design/methodology/approach

The study uses the Lerner index, defined through a translog specification, as a measure of market power. A system generalized method of moments technique accounts for the dynamic associations among the competition-concentration-stability nexus. The study further examines the moderating effect of ownership, size and capitalization on the nexus. The study also uses the Boone indicator and comments on the competition-bank stability relationship after controlling for bank governance.

Findings

The findings indicate that banks are less stable in a more competitive and higher concentrated environment. Exploring bank-level heterogeneity, first, the authors report that as competition increases, state-owned banks have greater incentives to undertake risky activities than private and foreign banks, which point to implicit sovereign guarantees that characterize the former. Second, the authors document an adverse influence of competition on the soundness of larger banks consistent with the “too-big-to-fail” assertion. Third, results corroborate the disciplinary role of regulatory capital and lend support to stricter capital norms under Basel III in a more competitive environment.

Originality/value

This paper is perhaps the first to capture competition and concentration in a single model; to reconcile conflicting evidence on competition-risk nexus; to shed light on the joint effect of competition and Basel accords for Indian banks.
