The theory of constraints is an approach to production planning and control that emphasizes on the constraints to increase throughput by effectively managing constraint resources. One application in theory of constraints is product mix decision. Product mix influences the performance measures in multi-product manufacturing system. This paper presents an alternative approach by using of goal pro...

introduction: this study aimed at examining body image and eating attitude with regard to reasons of exercising among non-athlete women attending sport centers. materials and methods: the present study has an ex-post facto design. 315 female sports center users were selected by multi-phase random clustering and completed the following rating scales: eating attitudes test-26 (eat-26), body image...

As experimentalists step up their pursuit of cold dark matter particles and neutrino masses, cosmological constraints are tightening. We compute the joint constraints on 11 cosmological parameters from cosmic microwave background and large scale structure data, and find that at 95% confidence, the total (cold+hot) dark matter density is hΩdm = 0.20 +.12 −.10 with at most 38% of it being hot (du...

Recently, Gargani and Refalo (G&R) presented an elegant model for the Steel Mill Slab Design Problem (Problem 38 in the CSP LIB). Contrary to earlier approaches, their model does not use 0/1 variables but exploits the traditional expressiveness of constraint programming. G&R indicated that static symmetry-breaking constraints proposed earlier are not effective on this model, as these interact w...

The paper proposes a dynamic method, Recursive Symmetry Breaking During Search (ReSBDS), for efficient partial symmetry breaking. We first demonstrate how Partial Symmetry Breaking During Search (ParSBDS) misses important pruning opportunities when given only a subset of symmetries to break. The investigation pinpoints the culprit and in turn suggests rectification. The main idea is to add extr...

This paper offers a simple and novel motivation for the Humean Theory of Reasons. According to the Humean Theory of Reasons, all reasons must be explained by some psychological state of the agent for whom they are reasons, such as a desire. This view is commonly thought1 to be motivated by a substantive theory about the power of reasons to motivate known as reason internalism, and a substantive...

Abstract Pattern-based reasons are for action deriving not from the features of our own actions, but larger patterns in which we might be participating. These relate to that will actually carried out, or they merely hypothetical patterns. In past work, I have argued accepting pattern-based reasons, together with a plausible account how weigh these can lead disastrous consequences. However, this...
