Service level risk in a pipeline system: a stochastic analysis

Article Abstract:

Union Gas Ltd. delivers natural gas to the North American market through iits systems facilities. The gas company's facilities planning assumes the Design Day concept, where facilities are evaluated on their ability to operate under extreme conditions. Subjecting the system to a probabilistic risk analysis reveals that the firm has a 0.09 probability of non-performance during winter and increases to 0.345 in the absence of winter. Thus, Union Gas must ensure that contracts and operations fall within these risk standards.

The Computer as an Aid to Physical Distribution Management

Article Abstract:

Best use of storage and distribution plants is a strong facet of the larger stock reduction problem. Money methods have been promulgated to form feasible layouts for boxes and pallets, but the practical problems encountered by those responsible for product design and distribution system constraints can be problematic to express using quantitative methods. Optimality and sensibility issues are analyzed. Palletization charts are featured. Tables of pack construction data are included.

Distribution planning for a divergent depotless two-echelon network under service constraints

Article Abstract:

A divergent two-echelon inventory model has been developed for creating an optimal planning procedure for a distribution system that consists of one central depot supplying a number of end stockpoints. The model relies on a decomposition algorithm to evaluate the ideal echelon order-up-to-level and allocation fractions. It is very useful for improving the service performance of various types of distribution systems.
