Due to the importance of greenhouse products in Jiroft County, this research was carried out to study the factors affecting adoption of Integrated Pest Management (IPM) operations by greenhouse owners, using Ordered Logit model, in 2014. The studied population consisted of 1650 greenhouse owners and the sample size was determined as 160 farmers, based on Cochran formula. Sampling method was pro...
dynamic cellular manufacturing systems, mixed-integer non-linear programming, production planning, manufacturing attributes this paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (dcms) based on production planning (pp) decisions and several manufacturing attributes. such an integrated dcms model with an extensive c...
Railway construction is one of the important activities in the development of any country and in developing countries, the need for roads is one of the main axes of development. Railway construction operations can effect on desert rangelands around railway. This study investigates the effects of Yazd-Eghlid railway construction on vegetation diversity and richness in the rangelands of Kalmand-...
Many construction processes are stochastic systems. A deterministic analysis of these systems may not allow for the random distribution of system events, resulting in poor or unrealistic system attributes. Two examples of such systems are the cyclic processes of earthmoving and concrete placing. While both processes have different objectives, their execution has much in common; in particular bo...
The thesis focuses on evaluating and improving the transport efficiency of two types of logistics operations in the supply chain. One research area is the production of raw material in heavy construction operations, which takes place early in the construction supply chain. The production of raw material, specifically earthmoving operations, involves the moving and processing of the soil surface...
