introduction: information management system is a formal approach to collect the necessary information in its due time for managers to facilitate decision-making, planning and management. medical records system which is closely associated with pieces of information and their true value can play an important role in health care organizations. the main objective of this study is to compare informa...

This study aims to develop a multi-period distribution system design model that provides an integrated view of the various costs, service quality and budget concerns within the planning horizon, as well as computationally feasible methods for obtaining solutions in realistic situations. The key design decisions considered in each period are: the number and location of distribution centers in t...

A modelling technique is developed for determining the harmonic voltage distribution across a distribution system when there is an equitable distribution of harmonic emission. The harmonic voltages at the 132kV and 415V levels are fixed to values based on IEC Compatibility and Planning Levels and the intermediate voltages determined. Studies are made of six systems, typical of Australian distri...

introduction: brachytherapy is a type of radiotherapy in which radioactive sources are used in proximity of tumors normally for treatment of malignancies in the head, prostate and cervix. materials and methods: the cs-137 selectron source is a low-dose-rate (ldr) brachytherapy source used in a remote afterloading system for treatment of different cancers. this system uses active and inactive sp...

The critical importance of integrating production, distribution, and inventory (POI) operations has long been recognized by top management of many companies. Now. using the latest advances in Management Science modeling and solution technology, an integrated computer-based POI system has saved approximately $18 million dollars during its first three years of implementation for a major national ...

Background: Intensity modulated radiation therapy (IMRT) is an advanced method for delivery of three dimensional therapies, which provides optimal dose distribution with giving multiple nonuniform fluency to the patient. The complex dose distribution of IMRT should be checked to ensure that the accurate dose is delivered. Today, film dosimetry is a powerful tool for radiotherapy treatment Quali...

this paper develops a model for distribution network expansion planning (dnep) considering reliability issues. with simultaneous switch placement and dnep, the proposed model tries to adequately consider the reliability issues in the planning stage in a way that the designed network has suitable performance from the reliability viewpoint. the reinforcement or installation of mv feeders and hv/m...

Objective: A process and system of treatment planning is very important in radiation therapy. The features of the software and the accuracy in the dose calculation and dose distribution will affect to the treatment quality as well as the patient outcome. When a treatment planning system is applied in treatment at the first time, it should be checked and approved all its system information, feat...
