The fundamental problem of inventory management is to decide economic order quantity and optimal order point in order to minimize the total inventory cost. There can be a number of inventory policies for that problem. In this study, these policies are analysed through inventory simulation model and fundamental inventory management model is established. For this model, possible policies in S company is evaluated by simulation and the optimal policy as determined. Simulation can be a very useful management tool if we recognize its application objects and methodological limits.
A Numerical Model Study of the Coastal Ocean Flow Due to the Turbulence Parameterization
유광우,YOU, KWANG WOO The Korean Society of Oceanography 1994 韓國海洋學會誌 Vol.29 No.1
A three-dimensional time-dependent coastal ocean model experiment of two different turbulence parameterizations is conducted. One of the turbulence parameterization is the constant eddy-mixing formulation, C1, and the other a stratification dependent eddy-mixing formulation, C2. The flow in C2 in strongly baroclinic, and limits vertical mixing of fresh and saline waters. The outflow discharged from an estuary is highly inertial and form a strong front of plume in C2 than that in C1. Because of the stronger outflow in C2, supercritical flow state, for which the near surface outflow velocity exceeds the baroclinic phase speed, can exist off the mouth of the estuary. The adjustment process of flow in the less saline waters are quite different for C1 and C2, which is dictated by the strongly baroclinic nature of the flow in C2.

A time-dependent primitive two0dimensional calculation is conducted to investigate the variations of Vol. transport onto the Yellow Sea and the Korea Strait with real bathymetries and to tract the Lagrangian movement of water particles. A series of experiment of the barotropic Kuroshio intrusions shows that the eddy induced branching of Kuroshio has sufficient intensity as to modify the continental shelf circulation. This intrusion seems to be one of the important forcing terms such as winds. tides and buoyancy that can also affect the dynamics in the region of the continental shelf. Transport variations across the shelfbreak due to the branching of Kuroshio which come particularly from the southwest of the Kyushu Island, have a strong relationship with the transport variations across the Korea Strait and in the southern area of the Yellow sea. The particle trajectories of the model results are well agreed with the trajectories of satellite tracking drifters obtained by one of the WOCE/TOGA program except the longer travel time period in the present model.

This paper reviews antecedents and outcome of ethical behavior in work organizations. Antecedents included are corporate ethical values, organizational justice and organizational commitment. Also, outcome is organizational citizenship behavior. Through the literature study, the paper suggests sequential causal relations among the above variables. In the framework of these causal relations, it proposes that corporate ethical values affect ethical behavior through other mediating variables, organizational justice and organizational commitment. Besides, it proposes the linkage between ethical behavior and a consequent variable, organizational citizenship behavior which have been considered to be related to organizational success. Finally, additional comments are made for future research.
