Abstract The layout of fixed-position assembly islands is widely used in the heavy equipment industry, where the product remains at one assembly island for its entire assembly period, while required workers, equipment, and materials are moved to the island according to the assembly plan. Such layout is not only suitable for producing bulky or fragile products, but also offers considerable flexibility and competitive operational efficiency for products with medium variety and volumes. However, du...

Abstract The intelligent manufacturing strategy and customer demand have mutually promoted each other. Also, the production mode is shifting towards customized production, and more rental resources or services are introduced to the production system, therefore, the systems are becoming more complex. Compared with traditional production systems, such systems have some new features, this work calls this type of system as a synchronized production operation system (SPOS). Under such circumstances, ...

Abstract Product lifecycle management (PLM) aims to seamlessly manage all products and information and knowledge generated throughout the product lifecycle for achieving business competitiveness. Conventionally, PLM is implemented based on standalone and centralized systems provided by software vendors. The information of PLM is hardly to be integrated and shared among the cooperating parties. It is difficult to meet the requirements of the openness, interoperability and decentralization of the ...

Abstract Most of the existing studies investigate the robot selection problem (RSP) in a multiple criteria decision making (MCDM) manner, from the viewpoint of a single person. This contradicts the reality that the robot selection decision is usually made by a committee or a group of experts with different expertise and concerns. For this reason, this paper proposes a group decision making (GDM) methodology for handling multiple criteria robot selection problem (MCRSP), the working process of wh...

Abstract An inventory transportation problem of manufacturing organization focusing on several stakeholders such as manufacturers, distributors, wholesalers, retailers and customers is addressed in this paper. The research study considered multi-echelon, multi-product, multi-modal and multi-period scenario. The mathematical model in the form of mixed integer non-linear programming is formulated to minimize the total cost associated with transportation, inventory holding and operational activitie...

Abstract In general, different divisions even in a same company may make scheduling decisions irrespective of the overall benefit of the company. It is practically impossible to carry out the integrated optimization, and the sequential optimization results in isolated solutions within the divisions often leads to inferior overall solutions. In this study, a novel bilevel approach is proposed for joint synchronized production and shipping scheduling, considering production division as the leader ...

Abstract In this paper, an on-site production time variation coordination is studied between a general contractor and a building contractor. To entice the building contractor to reduce its production time variation, which improves system performance but adds more pressure to the building contractor, a buffer space hedging (BSH) method is offered by the general contractor. The BSH is to reserve more spare space at an intermediate warehouse and serves for contingency usage. It can be an incentive ...

Generally, order punctuality has received plenty of attention by manufacturers in order fulfillment. In order fabrication, jobs from a customer are often separately processed in dispersed manufacturing resources, such as different machines, facilities, or factories. This leads to the difficulties of processing customer orders in a simultaneous manner. This paper proposes a concept of manufacturing synchronization (MfgSync) and measures it from the perspective of simultaneity and punctuality. We ...
