Towards just-in-time (JIT) production system through enhancing part preparation process

While firms are operating in a global competitive environment, they are subjected to changes because of the increased competitiveness and developed technologies. Therefore, this transformation process forces to produce with just-in-time production and low cost products or services and leads to customer satisfaction. Until today, competitive conditions, efficiency, productivity and quality of production, forced the firms to put more emphasis on production systems. Therefore, the firms are more interested in scientific analysis, planning and controlling of their production systems. As a result, one of the newest approaches is Just in Time (JIT) production system which emerged after WWII in Japan and aims to decrease the inventory cost and maximize the quality. The philosophy of this approach is to produce the necessary amount of production, when and where needed at the required quality.But JIT production system is weak in unclear species. For this purpose, the general and necessary solution is using fuzzy logic. In this paper we discussed about the simulation of an assembly line with 3 steps; firstly using Kanban production method, secondly non-using Kanban production method, and lastly using Kanban production method with fuzzy times. And also the comparisons of these steps will also be studied in this paper.

This paper discusses a method to determine optimum numbers of kanban in Just In Time production system and analyzes effect of optimum numbers of kanban to manufacturing performance. Method to determine kanban numbers was carried out by designing kanban flow based current situation, gathering relevant parameter on floor and company database, and calculating of kanban quantity through basic mathematical model. The basic mathematical model of kanban is derived according to designated kanban flow in JIT production system. The optimum number of kanbans would control and regulate material flow in manufacturing, thus JIT is achieved. As a result, product lead time and inventory stock level are improved. The conclusion is that an appropriate determination numbers of kanban could lead to optimizing manufacturing capability.

The Cost

Market competition that is not only in national scope, transportation and communication tool progress have encouraged global competition. Technology advance plays an importance role in short goods circulation and increasing various types of produced goods. This research aims to determine (1). Any non value Added activities leading to non value added costs in the company (2). The extent of benefits and roles of Just In Time (JIT) Method in eliminating all non value activities or sources (3). To provide description on the importance of Just In Time application for the company in order to improve efficiency and productivity. This research used descriptive method, namely the research giving description on certain activity or project systematically, factually and appropriately and there are also some necessary analyses to overcome any faced problems and to find out any alternatives that can be used to anticipate various developments to be adjusted with the theory. Results of the research conclude that (1). Success in reducing or making efficient production cost can be seen in sale by savings (2). The figure is obtained from comparison of cost of goods before the JIT production system implementation with the cost of goods after the JIT production system implementation. (3) by reducing cost of goods, it is expected that the company can reduce its cost of sale, with the aim to add product competitiveness in the market and the company will obtain increased level of profits. (4) it can be seen that before the implementation of JIT production system, the company profit has increased after the implementation of JIT production system.

The Right

Just in time (JIT) distribution is an necessary activity for the JIT production system ,which delivers the right parts with the right quality and quantities to the right place at the right time. In this paper we analyze and build a logistics distribution mode of a just-in-time based production system and develop a JIT production logistics information system using RFID technology, XML technology and .NET platform. The information system has four function modules: user management, basic data management, distribution management and interface management. The practice of JIT pull production shows that the rate of material distribution is effectively increased and the inventory is effectively decreased . The developed system and ERP system can control production process and material movement well .

Purpose The purpose of this paper is to compare principles from the original Toyota Production System (TPS), the Toyota Way 2001 and Kaizen philosophy with principles derived from Japanese Zen Buddhism. The paper would also like to enlarge the debate concerning some lessons learnt from Japanese culture in order to avoid Lean implementation failures. Design/methodology/approach The original English version of Taiichi Ohno’s book dedicated to the TPS, the Toyota Way 2001 and other relevant papers regarding Kaizen were reviewed and analyzed. The principles that emerged from the review of this literature were then compared with similar philosophical principles from Japanese Soto Zen Buddhism. The literature concerning Zen philosophy was methodically analyzed and categorized using the content analysis. Findings The results of this research show many theoretical parallelisms as well as lessons for practitioners, in particular referring to principles such as Jidoka, just-in-time, waste identification and elimination, challenge, Kaizen, Genchi Genbutsu, respect for people and teamwork. Research limitations/implications Analysis and results are mainly based on the literature that was found, reviewed and categorized, along with the knowledge of authors on Zen philosophy. Results could differ depending on the literature reviewed and categorized. Practical implications The results of this research bring food for thought to practitioners in terms of lessons learnt from Japanese culture, Toyota principles and management style in order to avoid Lean implementation failures. Originality/value This is one of the first papers which compares Lean-TPS and Kaizen principles with the Zen philosophy to try to learn lessons for succeeding in Lean implementation.
