dynamic lot size modelproduction planforecast datafixed data horizonIn the dynamic lot size model, the production plan for the first few periods is usually determined based on the forecast data for some fixed data horizon. This fixed data horizon may not be long enough, in the sense that ...
This paper studies the dynamic lot size model with speculative motive for holding inventory being allowed, where speculative motive means that producing a unit in a period and holding it to a future period may be cheaper than producing it at the later time. In a rolling horizon environment, on...
We refer to these models as the conventional DLS model. Inventory deterioration and short lifetime embody perishability of products. In the real world, a wide variety of commodities show the characteristic of inventory deterioration, such as agricultural, aquatic and marine products. Moreover, a ...
被引量: 19发表: 2007年 Models and Algorithms for Capacitated Lot Sizing Problems A single item dynamic lot size model with inventory capacity and lost sales is formulated. Subsequently, we extend a single item inventory capacity economic... X Liu 被引量: 5发表: 2004年 加载更多来源...
Without an object model that includes properties, such as the CommandBarControl object, most values for controls in a customization are set using the arguments that are defined in the callback code. We take a closer look at this model throughout this chapter. Ribbon Objects The callback routin...
RTTS is based on OO model and helps to describe and generate data types/data objects Thanks, Naimesh Patel Former Member 2013 Jul 03 5:42 AM 0 Kudos Yes, you are right in that pointers are different from C when you go to the technicalities like the addre...
It has been shown [32] that the main performance drawbacks of this execution model are virtual calls to the interface methods (e.g., MoveNext() and Current() in C♯♯, or hasNext() and next() in Java), which introduce non-negligible overhead, since they are executed for each ...
Full size image 4.2.5 Comparison with MPC The comparison between \({\overline{DMP}}^*\) and MPC based on the DMP model (DMP-MPC) is shown in Fig. 7. In both methods, we optimize w.r.t. the velocity and use a horizon of \(N=10\) points. The trajectory along the x axis is...
Full size image Dynamic property of thiourea network The dynamic nature of the thiourea bond is verified through an exchange reaction conducted with 1-hexyl-3-isopropyl-thiourea as the small molecular model compound. Its self-exchange reaction is expected to yield 1,3-diisopropylthiourea and 1,3...
