This paper examines the cost-reduction effect of “postponed” routing decisions in a two-echelon supply chain. When a delivery vehicle leaves the warehouse with system replenishment quantities, it sequentially makes routing decisions to choose the next retailer to visit. To measure this effect this paper studies combined vehicle routing and inventoryallocation policies designed to minimize total...

A data warehouse contains multiple views accessed by queries. One of the most important decisions in designing a data warehouse is the selection of materialized views for the purpose of efficiently implementing decision making. The search space for the selection of materialized views is exponentially large, therefore, heuristics have been used to search a small fraction of the space to get a ne...

<span>The availability of stock in the chicken egg supply chain is influenced by ability Agents to determine optimal orders suppliers. The number very important manage for Bogor City Egg Agent Indonesia because capacity reaches 340 crates. eggs at input variables, namely final (crate), selling price and consumer demand (crate) so that inventory under control. three variables have fuzzy va...

As the data sets increase in data warehouse day by day, the cost used for OLAP operations becomes extremely high. One of the most effective ways to solve this problem is to build appropriate materialized views in the data warehouse. In order to select the appropriate views to be materialized with the possible minimized cost, we propose a novel approach to the materialized view selection problem...

We propose a simulated annealing algorithm specifically tailored to optimise total retrieval times in a multi-level warehouse under complex pre-batched picking constraints. Experiments on real data from a picker-to-parts order picking process in the warehouse of a European manufacturer show that optimal storage assignments do not necessarily display features presumed in heuristics, such as clus...

As the need for strategic information is escalating at a tremendous rate worldwide, it has become a challenging task to manage the growing data and efficiently mine useful knowledge out of this raw data. Pattern Mining is one such technique to mine useful patterns out of the pattern warehouse. Patterns are the one way of knowledge representations. Few pattern generation and mining approaches ar...

Using the mathematic techniques such as Fuzzy approach has useful outcomes for production planning in different sources. In this paper LGP1 was used to model the objectives such as: avoidance of shortage or surplus of demand, access to maximum of income, using the normal capacity of production and organizing the inventory of warehouse, within the framework of Goal constraints like balancing b...

Data warehouses may contain multiple views accessed by queries. When these views are related to each other and deened over overlapping portions of the base data, it may be more eecient not to materialize all the views, but rather to materialize certain \shared" portions of the base data, from which the warehouse views can be derived. Selecting views to materialize is one of the most important d...

A data warehouse contains multiple views accessed by queries. One of the most important decisions in designing a data warehouse is the selection of materialized views for the purpose of eeciently implementing decision making. The search space for the selection of materialized views is exponentially large, therefore, heuristics have been used to search a small fraction of the space to get a near...
