Abstract

Purpose

The purpose of this paper is to investigate the economic feasibility of a three-echelon Halal Meat Supply Chain (HMSC) network that is monitored by a proposed radio frequency identification (RFID)-based management system for enhancing the integrity traceability of Halal meat products and to maximize the average integrity number of Halal meat products, maximize the return of investment (ROI), maximize the capacity utilization of facilities and minimize the total investment cost of the proposed RFID-monitoring system. The location-allocation problem of facilities needs also to be resolved in conjunction with the quantity flow of Halal meat products from farms to abattoirs and from abattoirs to retailers.

Design/methodology/approach

First, a deterministic multi-objective mixed integer linear programming model was developed and used for optimizing the proposed RFID-based HMSC network toward a comprised solution based on four conflicting objectives as described above. Second, a stochastic programming model was developed and used for examining the impact on the number of Halal meat products by altering the value of integrity percentage. The ε-constraint approach and the modified weighted sum approach were proposed for acquisition of non-inferior solutions obtained from the developed models. Furthermore, the Max-Min approach was used for selecting the best solution among them.

Findings

The research outcome shows the applicability of the developed models using a real case study. Based on the computational results, a reasonable ROI can be achievable by implementing RFID into the HMSC network.

Research limitations/implications

This work addresses interesting avenues for further research on exploring the HMSC network design under different types of uncertainties and transportation means. Also, environmentalism has been becoming increasingly a significant global problem in the present century. Thus, the presented model could be extended to include the environmental aspects as an objective function.

Practical implications

The model can be utilized for food supply chain designers. Also, it could be applied to realistic problems in the field of supply chain management.

Originality/value

Although there were a few studies focusing on the configuration of a number of HMSC networks, this area is overlooked by researchers. The study shows the developed methodology can be a useful tool for designers to determine a cost-effective design of food supply chain networks.

Abstract

Information technology companies are having to broaden their overall strategic view in deference to the premise that it is better to be market‐driven than technology‐led. Cost and technical performance are no longer the only considerations, as quality and service now demand equal recognition. The production of a high volume single item has given way to that of low volume multiple items, which in turn requires some modification of production systems and brings flexible manufacturing, Just‐in‐Time production and total quality control into sharper focus for the achievement of corporate objectives.

Abstract

Whole life costing analysis is becoming much more important as long‐term building owners and clients start to demand evidence of what their costs of ownership will be. It is also becoming more important as more private companies invest in private finance initiative (PFI), public private partnership (PPP) and prime contracting (PC) projects. One of the main barriers to the successful implementation of whole life costing (WLC), is the lack of reliable and consistent data on elements of whole life cost (capital, facilities management, and disposal) and the performance of building elements and services. The objective of this paper is to discuss the development of a consistent and flexible framework for collecting whole life cost data for buildings. A description of the taxonomy of the cost breakdown structure is given. The proposed data structure will be of value to all the project team (designer, contractor, facilities manager, supplier, etc.) who might be involved in traditional procurement or PFI, PPP, and PC projects. When the cost data structure is populated, it will provide the foundation from which the whole life costs of different alternatives can be estimated and from which the risks such as the technical and financial risks related to WLC elements, operational risks, etc. associated with, PFI, PPP and PC projects can be assessed and minimised.

Abstract

Purpose

Effective cost performance is a crucial criterion measuring successful project management in public-housing projects. This paper aims to analyse the vital underlying factors surrounding the successful cost management process (CMP) outcomes in public housing projects (PHPs).

Design/methodology/approach

The research was conducted in three stages. The first stage consisted of a detailed literature review to document success factors affecting cost performances and management. In stage two, brainstorming sessions were undertaken with construction experts knowledgeable in cost management practices and have been involved in PHPs. These sessions were used to refine those success factors for the PHPs settings and define their criticality with respect to the CMP stages using interpretive ranking process. In stage three, focus group sessions were performed to validate the interrelationships of the contextualised critical success factors.

Findings

The top three most critical factors for successful implementation and outcomes at all CMP stages in PHPs settings were found to relate to competencies, team qualities and collaborative practices of the project team. Early contractor involvement and effective construction planning and management also emerged relevant to the process.

Practical implications

Government project departments, project managers and construction organisations (consultants and contractors) need to commit and mandate continuous development of cost management competencies for all professionals engaged in PHPs. Channels supporting team integration and collaborative practices between design and construction teams are required to increase the likelihood of successful project cost management practice and outcomes in PHPs.

Originality/value

The research has developed a factor-process relationship model that can be used to improve and evaluate the efficacy of CMP implementation in PHP settings.

Abstract

Purpose

In light of the COVID-19 pandemic, all business sectors have critical needs. They face multiple challenges to restructuring their operations to build a resilient, cost-effective and sustainable supply chain. Therefore, this paper aims to investigate the practice and the research gaps related to supply chains.

Design/methodology/approach

This research paper is influenced by a literature review of the past decade. This review paper incorporates industry challenges of the COVID-19 pandemic, including future steps toward developing resilient supply chains in the new normal economy. The research provides a detailed framework for designing cost-effective survivable supply chains that withstand disruptions for the long term.

Findings

The proposed research focuses on the effects of the COVID-19 pandemic on supply chains and attempts to bridge pre and post COVID-19 research and practice gaps. Post-COVID-19 resilient supply chains need to be transformed into survivable supply chains. The survivability of the supply chain can be achieved by combining both supply chain resilience and supply chain viability measures. To the best of the authors’ belief, this is the first study that grounds a theory to provide interconnection of five critical supply chain concepts to manage supply chain risk. This study is uniquely positioned to develop a theoretical framework to design a cost-effective, resilient and sustainable supply chain by establishing the interconnection among these concepts in supply chains. This framework helps practitioners to implement the key strategies at the operational, tactical and strategic levels that enhance maturity in supply chains.

Research limitations/implications

The research findings are based on secondary reports such as industry reports, cases, research papers and expert opinions. The authors tried to consult with many companies. However, they were reluctant to share the recovery plan information from COVID. Also, as COVID still exists in many places in Canada, the authors could not gather every intended information from the companies. However, the authors have successfully shared the outcomes of this research with a reputed retail company in Canada. They recognized the importance of survivability in supply chains. Going forward, business organizations need to design cost-effective, sustainable and survivable supply chains.

Originality/value

The study attempts to unify current research dealing with supply chain resilience. The study concludes with the limitations of the current research. It highlights the prospects of future research and bridges the supply chain practice gaps from the challenges faced by industries due to COVID-19. The study contributes to the literature by identifying gaps to bridge the supply chain practice and reiterating new research directions to develop a cost-effective, survivable and sustainable supply chain.

Abstract

Purpose

The purpose of this paper is to find the optimum configuration of the composite launch tube currently being developed in Roketsan. The winding thicknesses and winding angles of the launch tube are selected as design variables, and three different composite material alternatives are evaluated: glass/epoxy, carbon/epoxy and aramid/epoxy.

Design/methodology/approach

In this study, structural optimization of a composite launch tube of man portable air defense system is conducted. To achieve a cost-effective design, a cost scoring table that includes structural weight, material cost, availability and manufacturability is first introduced. Then, optimization for minimum weight is conducted, where the winding thicknesses and winding angle are taken as design variables, and the safety factor value obtained by using the Tsai–Wu damage criterion is used as constraint. A surrogate-based optimization approach is used where various options for surrogate models are evaluated. Glass/epoxy, carbon/epoxy and aramid/epoxy are considered as alternative materials for the launch tube. Finally, the selection of the most cost-effective design is performed to achieve optimum cost.

Findings

Carbon fiber-reinforced epoxy matrix material provides the optimum cost-effective design for the launch tube.

Practical implications

The findings of the paper can be used to design more cost-efficient composite launch tube currently being developed in Roketsan.

Originality/value

The existing studies are based on a design approach to achieve minimum weight of the launch tubes, whereas this study introduces a design approach to achieve optimum cost.

Abstract

Purpose – The purpose of this paper is to help build up a relevant database for mapping technical and financial effectiveness of production in order to make cost‐effective maintenance decisions. Design/methodology/approach – A theoretical model is developed based on past research and experience adopting a holistic systems approach on the production. A case study, which includes databases of two maintenance‐used software programs, verifies the potential of applying the model. Findings – The main result achieved is a model for identifying relevant data required for accurate problem tracing and localisation within maintenance and production processes using a top down approach. The main conclusions are integration of IT and data resources within the enterprise is needed for developing a holistic view of the production process and a well‐formulated and documented procedure of data identification will ensure that the data can be traced back to root sources and in this way we can support the work of continuous cost‐effective improvement by eliminating root causes of problems at an early stage. Research limitations/implications – Further model verification by industrial case studies would be of interest. Practical implications – The holistic approach and the model presented are applicable especially in capital intensive industries, where maintenance budget is not negligible and the amount of data to process is large. By structuring the data need and data identification process relevant performance measures will be monitored and advanced maintenance concepts can be applied. Originality/value – By applying the proposed model in industry, the data identification process itself and not the data contents is necessary to be standardised and structured. It shifts the focus of the quality aspect from just data level to both data and data collection level. The performance measures will therefore not be chosen depending on what the IT applications can provide in first hand, but upon what is needed for cost‐effective mapping, analysis, following up and assessment of maintenance performance.

Abstract

Purpose

The purpose of this paper is to describe cost effective structural design procedures to support catalytic reactors used in hydrocarbon industry. Three case studies are presented using various reactor models. Modularization and transportation challenges are also discussed. The scope of the paper is limited only to the structural and construction aspects. The chemical and mechanical designs are not covered in this paper.

Design/methodology/approach

Finite element strategies are developed to model load transfer to reactor’s supports and to simulate soil/structure interaction. Fictitious nodes are generated at bolt locations to transfer the reactor’s loadings from the skirt to the pile cap. Soil-pile interaction is modeled using horizontal and vertical springs along the pile embedded length. Flexible supports are used at the bottom of the piles to stimulate the end bearing of the soil bed. The approach is demonstrated for several case studies of reactors support system.

Findings

The described algorithm is accurate and computationally efficient. Furthermore, the procedure can be used in practice for design catalytic reactor support.

Practical implications

The paper provides very useful guidelines that can be utilized in practice for design of catalytic reactor supports system. The procedure is cost effective and computationally efficient.

Originality/value

Extensive efforts were made in the past to develop economical procedures for catalytic reactors design. Much of the work focused on the process and mechanical aspects of catalytic reactors. Very limited work addressed the structural design aspects. Furthermore, no guidelines are available in current codes of practice.

Abstract

In recent years, there have been a growing number of projects and initiatives to promote the development and market introduction of low and net-zero energy solar homes and communities. These projects integrate active solar technologies to highly efficient houses to achieve very low levels of net-energy consumption. Although a reduction in the energy use of residential buildings can be achieved by relatively simple individual measures, to achieve very high levels of energy savings on a cost effective basis requires the coherent application of several measures, which together optimise the performance of the complete building system. This article examines the design process used to achieve high levels of energy performance in residential buildings. It examines the current design processes for houses used in a number of international initiatives. The research explores how building designs are optimised within the current design processes and discusses how the application of computerised optimisation techniques would provide architects, home-builders, and engineers with a powerful design tool for low and net-zero energy solar buildings.
