Assigning operations to feasible and suitable machine-tool combination is one of the significant problems in a flexible manufacturing system (FMS). This assignment affects on the total production costs and thus selecting the best combination is very significant for the system. This paper considers a multi-objective problem that minimizes the machining cost, setup cost and material handling cost...

In this paper, a multi-objective model is proposed to address the dynamic cellular manufacturing (DCM) formation problem. This model considers four conflicting objectives: relocation cost, machine utilization, material handling cost and maintenance cost. The model also considers the situation that some machines could be shared by more than one cell at the same period. A genetic algorithm is app...

background: today, the prevalence of musculoskeletal disorders is one of the health issues of concern in any society. one of the main causes of musculoskeletal disorders and conditions can be named unpleasant working conditions. the aim of this study was to report the prevalence of musculoskeletal disorders including working postures and lifting-related musculoskeletal disorders among workers o...

Mangosteen is a major Thai export produce which brings economic benefits to farmers. The objectives of this paper are to study the mangosteen supply chain in eastern Thailand and analyze the logistics cost structure for mangosteen farmers. The results show that the highest logistics cost consists of material handling such as post-harvest, grading, and handling, followed by transportation, procu...

A number of di€ erent performance measures have been used in the design and analysis of material handling systems. These performance measures have measured either: (1) the entire manufacturing system (e.g. job throughput), or (2) the material handling system independently (e.g. vehicle travel distance). The following is a review of performance, reliability, and performabilitymeasures used in th...

This paper presents a mathematical programming model for dynamic cell formation to minimize changeover-related costs (i.e., machine relocation costs and machine setup cost) and inter-cell material handling cost to cope with the volatile production environments in apparel manufacturing industry. The model is formulated through findings of a comprehensive literature review. Developed model is val...

We will present a progress report on our effort to develop a science-based design methodology for warehousing systems. In particular, we will discuss the hierarchical structure of our design procedure. This includes the decisions and parameters used in the master model, the various sub-models, and the decision and data interaction between the various levels in the hierarchy. We will present sev...

Manufacturing managers today are pressed by aggressive international competitors, high input factor prices, and customers who demand better quality at lower cost. In such an environment, there is a growing need to exploit the time, cost and quality advantages of cell manufacturing (Hyer and Wemmerliiv (1984)). Unfortunately, traditional cost accounting systems may be a major roadblock on the hi...

Purpose – The purpose of this paper is to provide a perspective of computer-aided material and process selection (MPS) software tools for product development purpose and present a practical approach for manufacturers and other decision makers involved in MPS. Design/methodology/approach – A multi-criteria deductive approach for MPS is applied to a case study by taking into account the technical...
