Software constitutes a major cost factor when developing technical systems. To reduce this cost, systematic reuse of assets is necessary from early on when developing similar products—an approach that has become known as software product line engineering. The automation of product derivation, that is, the automated product creation from core assets, is one of the success factors of product line...
Managing income is a considerable dimension in supply chain management in current economic atmosphere. Real world situation makes it inevitable not to design or redesign supply chain.

In this paper, we consider tactical planning for a class of the multi-period vehicle routing problem (MPVRP). This problem involves optimizing daily product collections from several production locations over a given planning horizon. In this context, a single vehicle routing plan for the whole horizon must be prepared, and the seasonal variations in the producers' supplies must be taken into ac...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
