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...

As a Micro, Small and Medium Enterprise that is engaged in the food business, namely crackers, raw material used Citra UMKM wheat flour which main making crackers. material. In this study, authors review controls to determine size of safety stock. availability materials for by comparing two systems. This study aims amount stock when reorder compare control system has been carried out using syst...

Language implementation frameworks, e.g., RPython and Truffle/Graal, are practical tools for creating efficient virtual machines, including a well-functioning just-in-time (JIT) compiler. It is demanding to support multitier JIT compilation in such framework language developers. This paper presents an idea generate threaded code by reusing existing meta-tracing compiler, as well interpreter des...

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...

The product quality is very important for long-term survival of a company. Therefore, the question of how much quality is enough seems relevant. During the late 1970s and early 1980s, the common answer of this question in western countries was to accept a small but allowable amount of poor quality in outgoing manufactured goods. The Japanese during same time chose a different course of action c...

Material handling is a loose loop in most assembly plants. Jiist-in-time (JIT) is a management philosophy that strives to eliminate sources of manufacturing waste by producing the right part in the right place at the right time. We propose to apply JIT principles to material handling in assembly plants. Material Kanbans are introduced as an effective means to control and balance the physical ma...

This article puts forth a networking paradigm, referred to as just-in-time (JIT) communication, support client-server applications with stringent request-response latency requirement. Of interest is not just the round-trip delay of network, but actual experienced by application. The JIT framework contains two salient features. At client side, communication layer will “pull” request from when th...

Purpose – The purpose of this paper is to explore if six sigma and lean are new methods, or if they are repackaged versions of previously popular methods – total quality management (TQM) and just-in-time (JIT). Design/methodology/approach – The study is based on a critical comparison of lean with JIT and six sigma with TQM, a study of the measure of the publication frequency – the number of aca...
