We describe a novel type of ordering phenomenon associated with the incommensurate occupational modulation of bistable molecular magnetic state in a spin-crossover material. This unusual type of aperiodicity resulting from the ordering of multistable electronic states opens new possibilities for addressing such materials by light. Here we show that light can switch the crystal from four- to thr...

In this paper we prove some stochastic comparisons results for progressive type II censored order statistics. The problem of stochastically comparing concomitants of the two progressive type II censored order statistics with possibly different schemes, under different kinds of dependence between X and Y is considered and it is proved that if Y is stochastically increasing (decreasing) in X, ...

How to develop material ordering and transferring plans in advance ensure smooth production of the enterprise is a major problem faced by actual process. In this paper, we make reasonable assumptions combining supply transshipment data previous years establish supply-transshipment model based on 0-1 planning. Firstly, selected Supply demand ratio, large order error rate, rate as evaluation inde...

This paper studies the raw material ordering and transportation strategy based on principle of integer programming. Based production data a certain enterprise, original attachment is firstly analyzed, 6 indicators are selected weight coefficient each indicator determined by TOPSIS entropy method. Then, 0-1 programming model for solving minimum number suppliers established, most economical schem...

Due to the complex and dynamic nature of the construction industry, construction material management faces many unique challenges from material planning, ordering, receiving and storing, handling and distribution, site usage and monitoring (Johnston and Brennan 1996). Poor material management has been identified as a major source for low construction productivity, cost overrun and delay (Fearon...

Due to the complex and dynamic nature of the construction industry, construction materials management (CMM) faces many unique challenges from material planning, ordering, receiving and storing, handling and distribution, site usage and monitoring. Poor materials management has been identified as a major source of low construction productivity, cost overrun and delays. Lack of active, accurate a...

this paper submitting the computation of optimize point of ordering in inventory control systems and particularly for continuous review of ordering system (r,q) by fuzzy logic method which similarly can be used for other ordering systems. since in the ordering models we cannot forecast the parameters like cost exactly, we have ambiguity. in this case using precise parameters may cause wrong dec...
