A comparison is given to determine the best quality improvement policy between those two policies considering profit sharing system. In the system, the manufacturer shares the profits to the supplier if the supplier can meet or exceed the quality target specified by the manufacturer.
Hence, profit sharing system is added in the model to strengthen the commitment of the suppliers in improving component quality. Quality improvement in the supply chain environment is also necessary. In the first policy, the rework is done by using the same manufacturing facility, while in the second policy a new process facility was added for rework. In this research, two rework policies are considered. To improve product’s quality, the decision of process target and its tolerance is important since it directly affects the defective rate, manufacturing cost, and loss to customer due to the deviation of product from its specification. You can sign up on at the bottom of the page, remember to select the interest category “Thermodynamics and Energy Technology”.The aim of this paper is to develop an optimization model for quality improvement by considering quality investment in rework policies and supply chain profit sharing.
If interested, you can also join our mailing list to get informed about releases of new software, and to get access to early preview versions. Read more about IPU and our services here. A large part of CoolPack is based on EES, and difficult to maintain. We do not develop CoolPack anymore, nor do we plan to do so in the future.
#Stage plot pro cost for mac
There is no more recent version of CoolPack that supports new refrigerants, nor is there a 64bit executable or a version for Mac or Linux.

Ideally, this new software would be supported by the community and receive continuous upgrades. The idea is to make a more modular software with different components that can be updated individually. It does not have all the same functionality as CoolPack has, but it comes with a lot of the new refrigerants built-in, and receives regular updates. Please have a look at the new CoolTools software, for calculations with new refrigerants. Note: Versions after v1.4.7 don’t contain functional changes, but only changes related to installation of the software. The CoolPack program is freeware and it may be distributed freely. So far we have included one transient element: simulation of the cooling of an object with the possibility of applying an on/off control of the compressor. Originally, it was programmed in Pascal but the present release is updated to Delphi. DALI was developed at the Refrigeration Laboratory (now part of Section of Thermal Energy at the Technical University of Denmark) in 1985. The dynamic elements are modeled and solved using a DAE-type simulation program called DALI. You can get more information about EES and F-Chart Software on the Internet. Alvarado, and is sold by F-Chart Software in Wisconsin, USA. “Tools” refers to that the programs are thought to be tools enabling you to make faster and more detailed system design and energy analysis.ĮES is developed by S.“Cool” refers to that the programs are related to the area of refrigeration.“EES” refers to the name of the program used to develop the simulation models (Engineering Equation Solver – EES).The name EESCoolTools is a combination of the three words EES, Cool and Tools: The first version of Refrigeration Utilities was released in 1995 and the program has since then been updated continuously with new refrigerants, more property plots etc.ĮESCoolTools has been formally introduced as part of CoolPack (March 1999). It consists of “Refrigeration Utilities”, “EESCoolTools”, and a transient element called “Dynamic”. Refrigerant calculations (property plots, thermodynamic & transport properties, comparison of refrigerants)Īs indicated by the name, CoolPack is a collection of simulation programs related to refrigeration.Transient simulation (cooling of an object/room).The following simulation purposes are covered: The development of CoolPack has until version 1.33 been financed by the Danish Energy Agency as part of the SysSim project. CoolPack was developed by the Department of Mechanical Engineering (MEK), Section of Thermal Energy (TES) at the Technical University of Denmark (DTU).
