مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...
determination of shipment quantity and distribution problem is an important subject in today’s business. this paper describes the inventory/distribution network design. the system addresses a class of distribution network design problem, which is characterized by multiple products family, multiple warehouses and retail-ers. the maximum capacity of vehicles and warehouses are also known. the res...
krytyn triplet alkyl esters ayzvsyanydha reactions and lead to the production of acetylene is stable.
in today's globalization, an effective integration of production and distribution plans into a unified framework is crucial for attaining competitive advantage. this paper addresses an integrated multi-product and multi-time period production/distribution planning problem for a two-echelon supply chain subject to the real-world variables and constraints. it is assumed that all transportations a...
Heritability and repeatability and genetic and phenotypic correlations were estimated for trotting race records with linear and generalized linear models using 510,519 records on 17,792 Finnhorses and 513,161 records on 25,536 Standardbred trotters. Heritability and repeatability were estimated for single racing time and earnings traits with linear models, and logarithmic scale was used for rac...
Distribution of distributed generation resources in distribution systems has several advantages, including reducing losses, improving voltage profiles, reducing pollution, and increasing system reliability. However, one of the most important points regarding the placement of these resources in distribution networks is economic issues and the return on investment and the increase in profits from...
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 ...
