The ultimate goal of inventory management is to decide the timing and the quantity of ordering in response to uncertain demands. Recently, some researchers have focused upon an impact of distortions in the information, e.g., customer order cancellation, on an economical inventory policy. The customer order cancellation is considered a kind of distortions in demands, because a demand that is eventually cancelled is equivalent to a phony demand. Also, there are some additional distortions in the inventory information. For instance, the procurement of suppliers may include some nonconforming items as a result of imperfect production and inspection by the suppliers, and/or damage in transit. The nonconforming item should be considered a kind of distortions in the inventory information, because the nonconforming item is equivalent to a phony stock. In this article, we consider an inventory model under the situation that customers can cancel their orders and the procurement of suppliers may include some nonconforming items. Then, we introduce the customer order reservation into the inventory model for the purpose of avoiding the costly backlogs, because the customer order reservation gives retailers a period to fulfill customer's requests. We formulate a periodic review (s, S) inventory model and investigate the economical operation under the situation mentioned above. Further, through the sensitivity analysis, we show the impact of these distortions and the effect of the customer order reservation on the inventory policy.

While the use of radiation in the medical field provides diagnosis and treatment with important benefits, we cannot deny that the radiation bombing causes some hindrances. The expansion of radiation use in modem medicine is essential, so the radiation use and preparation of proper measure for safety management has risen as a pressing subject. Therefore, in order to make defensive plans for the prevention of health obstacles to general users of radiation and for the provision of basic data of the health education programs to radiation workers by grasping the knowledge, attitude and behavior towards the radiation safety management of radiation workers in each medical institution and by analyzing the factors that affect the actions of radiation safety management, in this study we conducted questionnaires from September 26 to November 5, 2001 targeting 805 radiation workers in 108 medical institutions including university hospitals, general hospitals, hospitals, clinics and public health centers etc. located in Seoul, four metropolitan cities and small and medium cities, and has obtained the following results. 1. The average point of knowledge on the radiation safety management was 10.96 out of 15. As for the general characteristics, the level of knowledge on radiation safety management was higher with older age, high education background and longer career. 2. The average point of attitude on the radiation safety management was 66.36 out of 75. The attitude point for general characteristics were higher with higher education background, longer career and in case of universities, the level of attitude on the radiation safety management was high. 3. The average of action points on the radiation safety management was 56.09 out of 75. In general characteristics, the action level of radiation safety level was higher with older age, longer career, and the reception of radiation education and in case of university hospitals. 4. It is analyzed that the relation of knowledge, attitude and behavior on the radiation safety management is higher as the levels of knowledge and attitude on the radiation safety management is higher. 5.

The selection of suppliers and the determination of order quantities to be placed with those suppliers are important decisions in a supply chain. In this research, a non-linear mixed integer programming model is presented to select suppliers and determine the order quantities. The model considers the purchasing cost which takes into account quantity discount, the cost of transportation, the fixed cost for establishing suppliers, the cost for holding inventory, and the cost of receiving poor quality parts. The capacity constraints for suppliers, quality and lead-time requirements for the parts are also taken into account in the model. Since the purchasing cost, which is a decreasing step function of order quantities, introduces discontinuities to the non-linear objective function, it is not easy to employ traditional optimization methods. Thus, a heuristic algorithm, called particle swarm optimization (PSO), is used to find the (near) optimal solution. However, PSO usually generates initial solutions randomly. To improve the PSO solution quality, a heuristic procedure is proposed to find an initial solution based on the average unit cost including transportation, purchasing, inventory, and poor quality part cost. The results show that PSO with the proposed initial solution heuristic provides better solutions than those with PSO algorithm only.
