For each job (product instance) to be serviced in a product-reuse production system, multiple operations are often scheduled. Typically, there is high variability in the same operation times required by different jobs; and for each individual job, there is often significant probabilistic dependence (correlation) between many of the job’s required operation times. Well-conditioned jobs require f...
The purpose of this study was to explore how users perceive the affordances of an object from specific operation tasks. These affordances can be specified in terms of perceptual information. To this end, the eye-tracking technique was employed to capture what product parts uses’ fixation focused on when using a product for specific operational tasks. The results show that, for physical-behavior...
The recipe information describes the sequence of operations and the details of each operation associated with the manufacture of a product. In the early product development stage, the main objective is to identify operating parameters to give the best overall product yield. In the next stage, the recipe is verified on a pilot scale and expanded to include additional steps such as material prepa...
In recent years, machine learning techniques based on neural networks for mobile computing become increasingly popular. Classical multi-layer neural networks require matrix multiplications at each stage. Multiplication operation is not an energy efficient operation and consequently it drains the battery of the mobile device. In this paper, we propose a new energy efficient neural network with t...
Binary and unary operation preserving binary relations and quotients of those operations modulo equivalence relations are introduced. It is shown that the quotients inherit some important properties (commutativity, associativity, distributivity, ect.). Based on it the quotient (also called factor) lattice modulo filter (ie. modulo the equivalence relation w.r.t the filter) is introduced. Simila...
Cost of cement producing all over the world depends on to the level of wages, energy cost and availability of raw materials. By investigating financial statements of various companies at the stock market, the share of electrical and fuel costs are nearly 27 percent of total costs and this plays the important role in right management of energy consumption. In this regard mathematics modeling and...
This paper proposes a comprehensive, multi-objective, mixed-integer, nonlinear programming (MINLP) model for a cell formation problem (CFP) under fuzzy and dynamic conditions aiming at: (1) minimizing the total cost which consists of the costs of intercellular movements and subcontracting parts as well as the cost of purchasing, operation, maintenance and reconfiguration of machines, (2) maximi...
A kinetic model of a fixed bed tubular reactor incorporating catalyst deactivation was developed for the ISOMAX unit of Arak refinery. The kinetic parameters for the hydrocracking reactions over the commercial catalyst were determined using initial activity plant data i.e. when the catalyst is fresh. Catalyst deactivation was then taken into account by means of deactivation function based on pl...
Facing supply uncertainty of bulky wastes, the capacitated multi-product stochastic network design model for bulky waste recycling is proposed in this paper. The objective of this model is to minimize the first-stage total fixed costs and the expected value of the second-stage variable costs. The possibility of operation costs and transportation costs for bulky waste recycling is considered ...
For contemporary businesses to stay viable, business intelligence is mission critical. Although the importance of business intelligence is recognised, there is limited research on what information contributes to business intelligence and how business intelligence is sought for use in an organisational intranet. This research discusses how business intelligence is sought, captured and used havin...
