Purpose The purpose of this paper is to develop a mathematical model for designing the kitting system by determining optimum values related design parameters. Design/methodology/approach Main assembly feeding systems are explained with their advantages and disadvantages. Related literature reviewed gaps determined. To fill void be beneficial real life lean systems, elements in detail minimizing cost consisting Work In Process (WIP) number workers developed. A numerical example presented...

One-piece flow is a design rule that entails production in manufacturing cells on ‘make one, check and move-on one’ basis (Black, J.T., 2007. Design rules for implementing Toyota Production System. International Journal of Research, 45 (16), 3639–3664), which reduces lead time significantly. This paper proposes sequential methodology comprised mathematical model heuristic approach (HA) the hybrid cellular system (HMS), to facilitate one-piece practice. The employed cases small- medium-sized...

Purpose This paper aims to propose a combined methodology help decision makers in evaluating and selecting the most effective part feeding system. Design/methodology/approach As first step of methodology, hierarchical clustering analysis is applied design kitting or hybrid Second, activity-based costing determine which system better according their costs. Besides, sensitivity implemented observe behavior case takt time changes. Findings Using systems purely can lead problems because big...

This paper focuses on the batch scheduling problem in multi-hybrid cell manufacturing systems (MHCMS) a dual-resource constrained (DRC) setting, considering skilled workforce assignment (SWA). consists of finding sequence batches each cell, starting time batch, and assigning employees to operations accordance with desired objective. Because handling both decisions simultaneously presents challenging optimization problem, it is difficult solve formulated model, even for small-sized instances....

In order to respond part demands on time in an erratic demand environment, a complete road map for the design of hybrid cellular manufacturing systems (HMS) is proposed this study, based axiomatic (AD) principles, such that all functional requirements HMS are satisfied by corresponding parameters. With methodology, first, preliminary formed including exceptional operations. To facilitate one-piece flow within cells HMS, these exceptions eliminated decision rules, where alternative machines...

This study considers batch scheduling problem in the multi hybrid cell manufacturing system (MHCMS) taking into account worker resources.This consists of determining sequence batches, finding starting time each batch, and assigning workers to batches accordance with some pre-determined objectives.Due a lack studies on MHCMS, binary integer linear goal programming mathematical model is developed for bi-objective this study.The formulated difficult solve large sized instances.To model, we...

Mixed-model assembly lines (MMALs) are types of production that able to respond diversified costumers' demand for a variety models without holding large inventories. The effective utilisation mixed-model line requires the determination sequence different models. In this paper, two objectives considered in sequential manner, namely minimising: (i) total utility work, which means work from an additional worker assist operator completion task; and (ii) transfer states move segment line. First,...

Purpose The inherent variability on process times and demand are the factors that prevent efficient application of lean philosophy in multi-project product development (PD) environments. Considering this variability, a hybrid push–pull project control system is developed, value stream costing (VSC) analysis performed to reflect relation between lead time, capacity cost. assessment push/pull time improvement long-term savings have been aimed with proposed complete design structure....

This paper discusses the advantages of lot splitting in hybrid manufacturing environments where cellular and functional layouts are combined under Constant Work Process (CONWIP) production control. The proposed model fills a research gap related literature by applying pull simultaneously. A linear CONWIP control mathematical that minimises average flow time is developed case splitting. has sequence-dependent set-up times. demand level, coefficient variation (CV) impact reduction effect on...
