Production planning and control (PPC) systems have to deal with rising complexity and dynamics. The complexity of planning tasks is due to some existing multiple variables and dynamic factors derived from uncertainties surrounding the PPC. Although literatures on exact scheduling algorithms, simulation approaches, and heuristic methods are extensive in production planning, they seem to be ineff...

In building systems that acquire knowledge from tutorial instruction, progress depends on determining certain functional requirements and ways for them to be met. The Instructable Production System (IPS) Project has explored learning by building a series of experimental systems. These systems can be viewed as being designed to explore the satisfaction of some of the requirements, both by basic ...

Pubescent wheatgrass (Agropyron trichophorum (Link) Richt.) is growing in semiarid regions of Iran at altitude of 500 to 2000 m. Among different grasses growing in Iran, A. trichophorum is relatively resistant to grazing and defoliation as compared to other species of Agropyron genus which are dominant in the most summer rangelands. In Emam Gholi protected summer rang...

The objective was to test the hypothesis that more frequent but less accurately analyzed milk components may give a more representative measure of a cow's total lactation production. Daily records for milk production and fat and protein concentration collected by the AfiLab recording system (Afimilk, Kibbutz Afikim, Israel) from January 2014 to January 2016 from 47 large kibbutz (communal) herd...

the aim of this experiment was evaluating effect of fish oil versus palm oil on mammary gland health and milk production in holstein cows. ten multiparous holstein cows were used from six week before up to 63 days after parturition. feed intake and milk production were recorded daily, milk composition, body weight and body condition score were measured weekly and blood metabolites were determin...
