On July 5, 1997, environmental Protection Administration of Taiwan publicized the recycling regulation of waste home appliances that include four items, namely, television, refrigerator, washing machine, and air conditioner. It is believed that this regulation pioneers the law enforcement of waste home appliances in the world. To comply with tile policy, several contemporary waste disposal plants specialized in waste home appliances were established according to a follow-up technical specification oil the waste treatment facilities and methodology. Therefore, the traditional dismantling facilities were substituted and waste collection routes were altered as well accordingly. This study investigates the collection and recycling costs of waste home appliances in accordance with these newly established routes and facilities, respectively. Cost survey was conducted among collectors and recycling plants of waste home appliances; consequently, tire collection and recycling costs were analyzed, correspondingly. Results show that the recycling costs of waste home appliances were much higher than that of other waste items. Since the market share of recycled materials is lacking, these waste recycling plants of home appliances can only survive under the subsidy of EPA in Taiwan. Due to some arduous problems, the subsidiary system has already caused serious financial unbalance for a foundation under EPA of Taiwan, which associated with waste recycling in Taiwan.

In this paper, we investigate an inventory and production system in a three-layer supply chain system involving a single supplier, single manufacturer and multiple retailers. Earlier study in this type of supply chain only consider a single raw material in order to produce single item, but we consider raw materials in order to produce multiple items. It is assumed that the cycle time at each stage is an integer multiple of the adjacent downstream stage. We develop an iterative solution procedure to find the order quantity for the multiple items and raw materials that minimizes the supply chain-wide total cost per unit time of the supplier and manufacturer's raw materials ordering and holding, setup and finished items holding, the retailer's ordering and inventory holding. Numerical examples are presented to show that the proposed heuristic gives good performance.

The purposes of this study were to compare, through a factor analysis, the perceived level of importance of 4 categories of features relating to food service management between salespeople and clients, to establish an effective marketing strategy for successful contracting. To obtain data on the perceived level of importance level of the factors affecting foodservice management contracts, questionnaires were developed using the Delphi technique, which were modified by apilot test. The questionnaires consisted of 4 categories and 19 items on the factors affecting foodservice management contracts, with the importance level of these factors measured on a 5 point-Likert type scale. Between March 12 and April 13 2003, the self-administrative questionnaires were mailed to the 60 salespeople and 280 clients. A total of 50 clients (25%) and 48 salespeople(77%) responded to the questionnaires. As a result, forprivate contracts and in competitive biding, the differences of the perceived importance level between the salespeople and clients of the 3 categories (the appropriateness of foodservice operation plan, sales ability, the conditions and costs of the contract) were significant. For the 5 items relating to private contracts, Field trip, Menu Management Plan, Sanitation and Safety Management, Cost per meal and Food Cost per meal, both the salespeople and clients perceived high levels of importance for all these items. For competitive biding, both the salespeople and clients perceived high levels of importance for the 6 item the Foodservice operation supportive system, Field trip, Menu Management Plan, Renewal plans for interior and environment, Cost per meal and Food Cost per meal.
