Some Special Techniques in the Application of Dynamic Input-Occupancy-Output Models Liu Xinjian 1997, (2):  6-11.  Abstract ( 2313 )   PDF (290KB) ( 1425 )   Save This paper gives some special techniques to three problems: time-lags of investment,utilization factor of production capacity and the productive characteristic differences of inventory withfixed capital in the dynamic input-occupancy -output (I-O-O) models. The results will promote theapplication of dgnamic I-O-O models in practical economic analysis. References | Related Articles | Metrics

Decisiou on the Optimum Exercise Time of an American Call Option Liu Sifeng, Lin yi 1997, (2):  12-15.  Abstract ( 2173 )   PDF (198KB) ( 1348 )   Save Optimum excrcise time of an option is a very complicated metter. It is affected by manystochastic factors and so far have not been completely solved. In this paper, we discuss the optimum exercise time of an American call option by Markov transition probabilities under the supposition that stationary and uniform condition were satisfied. Sets of optimum exercise time about some common probabilitymodels have been studied. The conclusion in the theorem 3-6 can fairly suit to the actual situation of theoption exchange market. The main conclusion could be directly applied to stock and future exchange, project investment decision and some significant state strategic decision on science and technology, economy,political and military affairs and so on.

The Differences Between MRP Ⅱ and Stand-alone Finite Schedulers Jia Peishan 1997, (2):  14-21.  Abstract ( 2289 )   PDF (301KB) ( 1243 )   Save The relationship between finite schedulers which operate on output from a higher level in aconventional MRP Ⅱ system and so-called stand-alone schedulers which essentially operate directly onorders is discussed. Two graphical models-a demand flow model and a flowpipe model-are presented.The growth of the stand-alone scheduler is ascribed to the greatly increased computing power availablequite inexpensively on modern equipment.

Theory in Drift Linear Programiming and It’s Application Li Xin, Xu Jiuping 1997, (2):  36-41.  Abstract ( 2214 )   PDF (242KB) ( 1578 )   Save Upto now, there are many kinds and theory on grey linear programming,such as greyforecasting linear programming, grey target programmming, linear programming of grey intercal, andlinear programming with grey numbers [1~l7]. The objective of this paper is to deal with a kind of greydrift linear programming(GLP)through the mediums of procedure that turning GLP into parametriclinear programming via the mathematic programming. Some useful results for the benefit of solving GLPis expounded and proved, discussed and developed. References | Related Articles | Metrics
