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...

The process of product development in the textile and apparel industry usually needs several partners. These partners have to share and to communicate their ideas in a more and more efficient and time saving way. The internet technologies offer new fields for the application of a prototype (search engine) in a TRIAL project, called CREATIV[1]. The test bed is the so-called design network includ...

Apparel product development is an important stage in the life cycle of a product. Shortening this stage will help to reduce the costs of a garment. The aim of this study is to examine the production parameters in knitwear apparel companies by defining the unit costs, and developing a software to calculate the unit costs of garments and make the cost estimates. In this study, with the help of a ...

In this paper, to cope with the stochastic dynamic (or multi-period) problem, two new quadratic assignment-based mathematical models corresponding to the dynamic and static approaches are developed. The product demands are presumed to be dependent uncertain variables with normal distribution having known expectation, variance, and covariance that change from one period to the next one, randomly...

providing wider variety of products often leads to higher complexity in the manufacturing and business system. finding appropriate methods and techniques to manage these difficulties is going to be an attractive topic for researchers in operations management. by adopting a qualitative approach we have investigated the product variety management in the apparel supply chain. the main contribution...

The development of global supply chains during the last decade of the twentieth century has had a great impact on the apparel industry. Apparel industry firms face a wide array of challenges relating to the proliferation of product variety, changing product styles, shortened lead times, and reduced prices. As a result of these pressures, apparel companies have been forced to redesign their manu...

The apparel industry is a fashion industry with short product life and more demand uncertainty. Participants in apparel supply chain bear more risk. To lower the cost and risk for participants in apparel supply chain, a framework for apparel quick response system based on collaborative forecasting was proposed. The prototype of the apparel quick response system was provided, which included thre...

Based on the real-world inventory control problem of a capacitated healthcare apparel service centre in Hong Kong which provides tailor-made apparel-making services for the elderly and disabled people, this paper studies a partial backordered continuous review inventory control problem in which the product demand follows a Poisson process with a constant lead time. The system is controlled by a...

In the design process of gratings, the grating layout design is the most important activity in influencing manufacturing cost. In the grating layout design, the key to saving manufacturing cost is to find a design with a minimal number of cutting operations. This paper presents an application of the A* algorithm in grating layout design. The design problem is represented as the space search pro...
