Research interests have been focused on the concept of penalizing jobs both for being early and for being tardy because not only of modern competitive industrial challenges of providing a variety of products at a very low cost by smoothing productions but also of its increasing and exciting computer applications. Here, sequencing approaches of the mixed- model just-in-time production systems is...

This paper discusses a single-item, multi-stage, serial Just-in-Time (JIT) production system with stochastic demand and production capacities. The JIT production system is modeled as a discrete-time, M/G/1type Markov chain. A necessary and sufficient condition, or a stability condition, under which the system has a steady-state distribution is derived. A performance evaluation algorithm is then...

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...

A dynamic systems approach is proposed to investigate challenges of implementing production leve and associated costs. A model of a lean cell is developed using system dynamics. The model capt various lean tools influencing production levelling. Comparative cost analysis between various leve implementation policies for stochastic demand with multiple products is conducted. Results showed determ...

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...

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...

AMPROS is a project which aims to study and develop a middleware-based platform for mobile environments. AMPROS provides a distributed, just-in-time, and contextaware deployment of component-based applications. The deployment adaptation is carried out by a set of adaptive components able to vary the architecture of the application as well as the attributes of its components. In this paper we de...
