This research studies the single-stage supply chain system operated under JIT technique. A kanban mechanism is employed to assist in linking the production processes in a supply chain system. The number of kanbans, batch size, and the number of batches are determined optimally. Based on this information, kanban operation between two adjacent plants can be worked out for controlling the supply c...

A practical method of JIT modelling for a blast furnace process data whose characteristics are very complicated physical phenomena and stiff nonlinear process are studied. The proposed method is composed of severely selecting process data variables by stepwise method and searching the past similar data in quantized topological space constructed by the selected variables. The effectiveness of th...

The focus on the sequential nature of the improvement initiatives has neglected the synergistic effects among practices and literature lacks research on complementarity between internal and external bundles of practices. The aim of this paper is to test the existence of complementarity among internal and external just-in-time bundles. We run statistical analysis using the third round of High Pe...

The Toyota production system (TPS) or lean has long been regarded as a powerful approach for managing manufacturing factories. However, in the early 1990s, the TPS was found not to work when it was applied to Japanese electronics companies. TPS is fit for a stable, but not volatile, business environment such as that which the electronics industry belongs. This volatile environment can be descri...

Effective and efficient material handling (MH) system is crucial in any Just in Time (JIT) production system. A Gravity Flow Rack (GFR) system is one of the very well adopted MH system and very practical in order to optimize the effectiveness of the JIT production system. This paper presents a review on the actual implementation of a GFR system at an automotive component’s assembly line in an a...

This paper presents a new mathematical programming model for the bi-criteria mixed-model assembly line balancing problem in a just-in-time (JIT) production system. There is a set of criteria to judge sequences of the product mix in terms of the effective utilization of the system. The primary goal of this model is to minimize the setup cost and the stoppage assembly line cost, simultaneously. B...

This study built a simple, linear, four or fivecell production line model using the SIMAN/ Arena modeling tool. We used information from a case study of a real-world production line, augmented, as necessary, with details of machine operating characteristics not available in the original case study. The model was created in five variants: Traditional, JIT without kanban, JIT with kanban, TOC app...

Although the theoretical debate concerning firms' boundaries is far from resolved, the empirical shape of the firm has been largely redefined over the past two decades. Companies have focused on their 'core competencies'. This specialisation research has caused a trend towards vertical disintegration leading to a reorganisation of the value chain (Porter, 1990). More specifically, empirical sur...
