Lean supply chain practices in the Halal food

Purpose – This study aims to assess the possibility of implementing lean practices in the Halal food supply chain, and the barriers to their implementation. Design/methodology/approach – A survey was used to identify the perceived issues and attitudes towards implementing lean practices in the supply chain. The questionnaire was distributed to 300 Halal food firms in Malaysia. A total of 61 usable replies were received. Findings – More than 70 percent of the firms reported that lean supply chain (LSC) has not yet been implemented in their firm. Data analysis shows that 14 percent of non-lean firms urgently need to implement lean manufacturing. Market competition and uncertainty was highlighted as an important barrier in implementing LSC among lean firms. In contrast, lack of customer awareness of LSCM practices was recognised as a major barrier in non-lean firms. Originality/value – There is little documentation regarding the status of LSC implementation in the Halal food industries, and therefore identif...

Review of supply chain performance measurement systems

In todays competitive business environment, supply chain performance is one of the most critical issues in various industries. It is argued that supply chain performance measurement is fundamental to efficient supply chain management. Over the past two decades, several frameworks and systems have been developed to meet this need. This study reviews the literature in the field of supply chain performance measurement and assembles an overview of those systems, approaches, techniques and criteria. For this purpose, 83 of 374 related articles from 1998 to 2015 were selected for final review using the Scopus and ISI databases. Findings disclose that performance measurement in supply chain contexts is still a fruitful area of research. The study also provides an overview of the performance measures employed in supply chain systems. These findings present a solid basis for future academic and practitioner work in the field of supply chain performance measurement.

RFID impacts on barriers affecting lean manufacturing

Purpose Lean manufacturing is one of the leading paradigms for fast and proficient manufacturing but its proper implementation is a foremost task due to certain barriers affecting lean and can be handled when utilized with RFID technology. With this aspect in view, the purpose of this paper is to enlighten and present a thorough literature study that can show how RFID-based lean manufacturing is helpful for handling barriers affecting lean manufacturing in light of previous literature available. Design/methodology/approach In order to achieve this purpose a systematic literature review is conducted to justify the impacts of RFID technology for handling barriers. The aim of this systematic literature review is to initially find the barriers affecting lean implementation and then to explain the properties of RFID-based lean manufacturing which are highly feasible to handle detected barriers. Findings An interrelation is generated in this study which provides a clear indication that the properties of RFID carry significant effects to handle detected barriers in the operational, managerial and financial regime of manufacturing companies. The detected barriers that affect lean implementation are company’s cultures, top management commitment, poor employee administration, lack of finances, unbalanced inventory control, unstable customer handling and longer lead times. The properties of RFID-based lean manufacturing like operational visibility, inventory control, production control, minimized lead times and the real-time data information (to facilitate top management and employees on shop floor) are extremely helpful to control these barriers. Originality/value The originality of this study is the provision of clarity provided to both academicians and practitioners by citing and utilizing previous research studies which undoubtedly indicates positive impacts of RFID on lean implementation.

A systematic review of lean implementation approaches: a proposed technology combined lean implementation framework

Nowadays, lean implementation seems to be very effective when combined with technologies like radio frequency identification (RFID) but a gap has been observed regarding the availability of certain lean implementation approaches that practice this confluence. Keeping this requirement in view, an extensive systematic literature study has been conducted to first confirm this gap and then to propose an implementation approach by selecting the right approach, methodologies, tools and steps from previous literature. In order to achieve this task, 39 most relevant previous lean implementation approaches have been selected through rigorous search and selection (based on studying their originality, methodology, objectives and limitations) which first confirmed the gap and then enlighten that 56% of previous implementation approaches have utilised ‘implementation framework’ as the most common approach and the common methodologies utilised were case study and literature review. Moreover, about 25.6% of previous approaches have utilised Value Stream Mapping (VSM) for lean implementation and Technology-Organisation-Environment (TOE) framework was considered as the most appropriate methodology for RFID deployment. So, these statistics were further utilised to invent an implementation framework comprising 21 steps and four implementation phases in which confluence of VSM and TOE has been effectively utilised to achieve successful deployment of technology combined lean.

Understanding of empty container movement: A study on a bottleneck at an off-dock depot

Port not only function as connections between marine and land transportation but also as core business areas. In a port terminal, available space is limited, but the influx of container is growing. The off-dock depot is one of the key supply chain players that hold empty containers in the inventory. Therefore, this paper aims to identify the main factors of bottlenecks or congestion that hinder the rapid movement of empty containers from the off-dock depot to the customers. Thirty interviews were conducted with individuals who are key players in the container supply chain. The data were analyzed using Atlas.ti software and the analytic hierarchy process to rank the priority factors of bottlenecks. Findings show that several pertinent factors act as barriers to the key players in the container movement in the day-to-day operations. In future studies, strategies to overcome fragmentation in the container supply chain and logistics must be determined.

An uncertain mathematical model to maximize profit of the defective goods supply chain by selecting appropriate suppliers

This study presents an uncertain mathematical model for maximizing profit of the defective goods supply chain during uncertain situations by using selection of appropriate suppliers, just-in-time (JIT) logistic philosophy and minimizing total costs including costs of production, shipping, holding, defective goods, scrap goods, shortage in retailers. The selections of suppliers are based on three criteria, namely, quality, JIT delivery, and level of responsibility, which have important roles in the production of perfect goods by manufacturers. In each criterion, two kinds of indicators are considered by manufacturers. The first indicator is the importance of the weighted factor of each criterion for each manufacturer, and the second is weighted factor of each supplier with respect to each criterion. The proposed mathematical model with uncertain parameters and the probability of occurring in various scenarios is investigated. The model is studied in ten scenarios and the average amount is calculated. The mentioned mathematical model is solved by the averages of the parameters using CPLEX.12 solver and Expert Choice software. The findings of the model are maximum profit, amounts of economic production quantity, defective goods, scrap goods, and amounts of products that should be exchanged among the nodes of the supply chain. To achieve maximum benefit, the model can select the appropriate suppliers. The results obtained demonstrate the validity and efficiency of the proposed uncertain mathematical model.
