Analytical Optimization for the Warehouse Sizing Problem Under Class-Based Storage Policy

the algorithm for solving the inverse numerical range problem

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

Optimal placement of warehouse cross aisles in a picker-to-part warehouse with class-based storage

Given a picker-to-part warehouse having a simple rectilinear aisle arrangement with north2 south storage aisles and east-west travel aisles (or “cross aisles”), this paper investigates the 3 optimal placement of the cross aisles as a consequence of the probability density function of the 4 order pick locations, as determined by the storage policy. That is, for a given storage policy, 5 what pla...

A Linear Storage-Retrieval Policy for Robust Warehouse Management

Assigning products to and retrieving them from proper storage locations in a unit-load warehouse are crucial in minimizing its operating cost. The problem becomes intractable when the warehouse faces uncertain demand in a dynamic setting. We assume a factor-based demand model in which demand for each product in each period is affinely dependent on some uncertain factors. The distributions of th...

Duality for the class of a multiobjective problem with support functions under $K$-$G_f$-invexity assumptions

‎In this article‎, ‎we formulate two dual models Wolfe and Mond-Weir related to symmetric nondifferentiable multiobjective programming problems‎. ‎Furthermore‎, ‎weak‎, ‎strong and converse duality results are established under $K$-$G_f$-invexity assumptions‎. ‎Nontrivial examples have also been depicted to illustrate the theorems obtained in the paper‎. ‎Results established in this paper unify...
