The purpose of this research is to deal with the problem of two-stage assembly flow shop scheduling. A number of single-item products (identical) each formed of several different parts are ordered. Each part has m operations done at the first stage with m different machines. After manufacturing the parts, they are assembled into a final product with some non-identical machines. The purpose of ...
the inventory routing problem (irp) arises in the context of vendor-managed systems. this problem addresses jointly solving an inventory management problem and a vehicle routing problem. in this paper, we consider a multi-depot multi-vehicle inventory routing problem in which suppliers produce one type of product to be delivered to customers during a finite time horizon. we propose a two-phase ...
Background and Aim: Mind map is a full-color illustrated note-taking in which, main idea or subject is situated. The main ideas then branch out from the center, which are linked to the central idea. This is a relatively new topic, and slight research has been conducted to show its effectiveness worldwide. The aim is to examine the effectiveness of mind maps in the information retrieval process....
هدف: این مطالعه به منظور بررسی ارتباط میان علائم بیماران و stage کارسینوم معده در بیماران مراجعه کننده به بیمارستان امیرالمومنین تهران طی سالهای 90-89 انجام شده است. روش مطالعه: در این مطالعه مقطعی، 30 فرد مبتلا به سرطان معده بررسی شدند که افراد از نظر staging بررسی شده و stage آنها ثبت گردید و در نهایت فراوانی علائم بالینی مختلف در stageهای مختلف مورد مقایسه قرار گرفت. یافته ها: 7/6 درصد در ...
ultra-wideband (uwb) radio is a promising technology for low-cost, high-rate communications at short ranges. however, high bandwidth and low power of the uwb signals impose some difficult challenges in signal processing and implementation of the receiver. acquisition of the signal timing is the first task to be performed in a coherent receiver. the high bandwidth of uwb signals demand for fine ...
This paper presents a two-stage intelligent search algorithm for a two-dimensional strip packing problem without guillotine constraint. In the first stage, a heuristic algorithm is proposed, which is based on a simple scoring rule that selects one rectangle from all rectangles to be packed, for a given space. In the second stage, a local search and a simulated annealing algorithm are combined t...
