The above paper proposes a method to design optimal control places with self-loops for flexible manufacturing systems by solving an integer linear programming problem (ILPP) at each iteration. However, some constraints in the ILPP are redundant. This technical correspondence shows that they can be removed without changing the feasible region of the ILPP.
The aim of this paper is to present a mathematical approach to support the decision making of distribution center location. We use the LP model to decide the (distribution center) DC's capacity and location with the consideration of delivery time. We find that the time cost effects decision of distribution center location significantly and suggest that manager should involve cost of time in their...
This study proposes a new inventory model of deteriorating items with price reduction and backlog. In this paper, both pricing and backlog are considered. It proposes the solution procedure for the new model, and conducts one numerical example to verify the effectiveness of the new inventory model. Finally, it provides some potential issues for future research.
This study focuses on the single-cycle stock replenishment strategies of perishable merchandise with price reduction, in which the stock shortage is permissible. It proposes a new Economic Order Quantity (EOQ) model, and conducts one numerical example to show the effectiveness of the new EOQ model. Finally, it provides some potential issues for future research.
RZ-DPSK to NRZ-DPSK format conversion in a silicon microring resonator is demonstrated experimentally for the first time at 41.6 Gb/s. The converted signal eye diagrams and bit-error-rate measurements show the good performance of the scheme.
In order to restrain the adverse influence of speed mutation and torque ripple when brushless dc motor runs at the commutation moment, at the same time, for the sake of avoiding the fact that traditional PI control tragedy highly depends on the precise mathematical model of the controlled system, this paper puts forward a kind of control tragedy of domain self-regulating fuzzy control. At first, the...
Ecology is a branch of biology concerned with the relations between organisms and their environment. Educational ecology is the study of the disciplines of education, using the scientific thinking of the study of relations between biological and environmental. There are many problems in practical applications of network education as the third generation of distance education, such as the simple relocation...
