But the problem is not restricted to single machine single-step deterioration, but also to settings of multi-machine and multi-step degradation.

TL;DR: In this paper, a series of nonlinear time/cost tradeoff models for project management is developed and then extended to include other operational considerations, such as the use of non-linear functions to describe time and cost relationships in project scheduling environments.

TL;DR: In this article, a new algorithm to group the mating parts based on the ideas of balanced probability and unequal tolerance range in each group is presented. But, there are often surplus parts in some groups due to the imbalance of mating parts, especially in the cases of undesired dimensional distributions.

TL;DR: In this paper, a tabu search-based cell formation algorithm is proposed to group machines into cells such that the material movement between cells is minimized, and the cell formation problem is modeled as a graph partition problem.

TL;DR: In this paper, unit load automated storage/retrieval (AS/R) systems are compared using system throughput as the primary criterion; other performance measures investigated are storage and retrieval waiting times, and rejects due to the rack or input/output queues being fully utilized.

TL;DR: In this paper, the earliness/tardiness production planning problems for mass and one-of-a-kind product manufacturing systems with capacity constraints, separately, are investigated. And a branch-and-bound algorithm is used to check the performance of the heuristic algorithm.

TL;DR: A coal blending management system incorporating a goal programming (GP) model that determines appropriate quantities of coal from different stockpiles for a consistent feeding of blended coal while meeting environmental and boiler performance requirements is presented.

TL;DR: A new methodology for flexible process sequencing using a Petri net based approach and linearizing a flexible process sequence using T-INVARIANT analysis is presented.

TL;DR: The ART II and BP paradigms are used as exemplars of ANNs developed using supervised and unsupervised learning to classify the 48 states in the continental U.S.A. based on location profiles developed from government publications.

TL;DR: A model based on variable redefinition is developed leading to a solution strategy based on a branch-and-bound search with sharp low bounds, which is very efficient in terms of computation time and attributable to the sharpness of the lower bounds, the efficiency with which the low bound problems are solved and the frequent generation of good upper bounds.

TL;DR: In this article, the EOQ model is aggregated into an extended composite model by including shipping costs, inspection costs, in-transit holding costs, backorder costs, finite replenishment, quality rejects, quantity discounts, and freight rate discounts in its formulation.

TL;DR: In this paper, the authors propose a pocketing procedure for machining free-form pockets with multiple islands, where a pocket is assumed to have a pocket boundary and island boundaries defined by closed cubic B-spline curves.

TL;DR: In this paper, the authors developed a method of replication coupled with the use of the quality confidence intervals in order to generate invigorating debates on a particular issue before weight assignments are made.

TL;DR: In this paper, an optimal control approach to continuous-time aggregate production planning problems is presented, which describes the production and capacity evolution (expansion, sell and deterioration) processes in the form of differential equations with regular production, subcontracting and capacity change rates controllable on one hierarchical level.

TL;DR: A perspective on proactive maintenance by monitoring the degradation of manufacturing equipment and systems is presented and illustrated in this paper, where various methods in modern computer-aided maintenance including machine monitoring, fault detection and fault diagnostics are examined.
