Current Computer integrated manufacturing/Enterprise Resource Planning (CIM/ERP) systems require harmony and communication between humans and facilities. A user's preferences should also be considered in CIM/ERP systems. Virtual factory (VF), also known as virtual manufacturing (VM), systems can fulfill the requirements of current CIM/ERP systems. A VF system simulates virtual production in a virtual factory environment on the computer system which allows optimization prior to going into production. In this paper, we defined a VF system as a pre-analyzing system for designing, engineering and manufacturing a product in the enterprise system of the real world. The objective of this paper is to design a VF system and to develop a prototype system that the customer can participate in and be satisfied with. We selected a telephone as a sample product for the VF system. The VF system consists of four subsystems: virtual product ordering, design, manufacturing, and CIM/ERP interface. The prototype system aims to develop a virtual product ordering and design system.Keywords (CIM/ERP) 9 Kansei engineering 9 Virtual factory 9 Virtual product ordering IntroductionWith the development of production technology, customers are no longer only searching for goods which satisfy physical requirements such as quality and function, but also those that meet psychological requirements like feeling and emotion.

The decision variables in the (s, S ) inventory system are s (ordering point) and S (maximum inventory level). In this paper, we propose a new ordering model in the (s, S ) inventory system for the mixed part transportation problem with multi-item based on the depot system. The order range is introduced and used as decision parameters instead of the order point for ordering multi-item. Finally we test the proposed model with a numerical example and show computational results that verify the effectiveness of the model.

Ordering multi-items from a vendor is a standard business practice. It is also common for a purchaser to have some constraints such as a budgetary limitation, warehouse capacity restriction or transportation problems. As a result, the problem of making ordering decisions for multi-items with various constraints is regarded as an important issue on the inventory management. In this paper, we propose a new ordering model for multi-items with the mixed parts transportation problem based on the warehouse system. Order range is especially introduced and used as decision parameters instead of order point to order multi-items. Finally, a numerical example and computational results are given to illustrate the proposed model.
