The notion of derivation in a lattice implication algebra is introduced, and some related properties are discussed. The properties of the isotone derivations are mainly researched. Using the concept of derivations as defined, a class of lattice implication algebras is constructed.

The buffer allocation problem, i.e. how to distribute a certain amount of buffers among the buffer locations of a production line, is an NP-hard combinatorial optimization problem. In this study, a hybrid approach combining simulated annealing and genetic algorithms is presented to find optimal buffer sizes for unreliable production lines. The objective is to improve the capacity of production line by implementing proposed hybrid approach. To evaluate the capacity of the line, a detailed simulation model is developed. Numerical examples are given for evaluating the performance of the proposed heuristic, traditional genetic algorithm, and simulated annealing procedures. The results show that the proposed hybrid approach gives good solutions in reasonably short computation times.

Grassland fire simulation is complex because of many influence input parameters. Based on the field data of grassland fire behavior, the paper simulated the spread process of the grassland fire applying GIS tools. Applying experimental data, the study established initial grassland fire speed in control environment at first, and then calculated grassland fire spread speed rate in different wind speed, wind direction, and slope. The study obtained the grassland fire spread speed model applying composition of forces. Finally, the study calculated grassland fire spread time in large-scale grassland spatial. Take the severe grassland fire disaster of Dongwuqi in May 16, 2005 as a cases, comparing with actual results, this model showed reliable, and this model can provides decision-making for grassland fire management department.

It was proposed in the former research that chaos control can be used to suppress electromagnetic interference (EMI) in DC-DC converters. Here, a practical application in a power supply ATX is to be given to show that inputting an external chaotic signal to a Pulse Width Modulation (PWM) control circuit can reduce EMI by spreading the spectra of switch voltage, transformer current and output inductor current over the whole frequency band.

In this paper a new software monitor is presented. computer systems must be adequately monitored to ensure stability control, reliability and risks to unexpected problems. Classic monitors are based on the analysis of some key variables which are in change during operation of the systems. In this new monitor, some modeling techniques (statistics, reliability and decision making) are used to provide an easy, automated way for the intervention into a system under risk.

We present some new induced and heavy aggregation operators in a unified framework between the weighted average and the ordered weighted average. We introduce the induced heavy ordered weighted averaging weighted average operator. It is an aggregation operator that provides a parameterized family of aggregation operators between the minimum and the total operator. It considers complex reordering processes assessed with order inducing variables. We study some of its main properties and particular cases.

In this paper, we provide a decision support system for a two-echelon spare parts inventory distribution system that consists of a single central warehouse and a local warehouse. These warehouses are organized as separate entities that make their individual spare parts inventory provisioning decisions independently. The goal is to minimize the total backorders seen by the local warehouse such that the total inventory investment does not exceed a given budget. We provide a decision support system that can be used to coordinate these warehouses in a way to reach this goal. We used a real-life case data obtained from an original equipment manufacturer located in Europe and provided numerical results.

Today's companies, perform a work which aims to enhance individual and corporate efficiency and effectiveness. Companies need to provide establish and provide valid and applicable performance management system in order to become successful on sectoral. In a competitive environment, companies' staff performance evaluation as indicate retrospective performance level, identify prudential potential performance and provide new perspective to studies about enhance performance. The purpose of this study is to specify the recruitment criteria of position that clinical chief of surgery. Research is done on a group including 2 experts that have a career in health sector for many years. In this research, staff recruitment criteria, recruitment process evaluation and the ranking of importance for the corporation are involved for the non-profit organization. This study includes identifying the criteria for selection, some information about criteria are get from the experts which working at hospitals in Istanbul then all in information are combined to build hierarchy of recruitment criteria. By using Analytical Hierarchy Process (AHP) in fuzzy environment criteria are ranked and the importance is identified and this method is used to select appropriate candidate for the position. As a result, according to FAHP methods recruitment criteria and process evaluation for the surgeons are identified.

Keyword suggestion methods are important to effectively match the keywords chosen by the advertisers and the queries in search engine advertising. Existing keyword suggestion methods can only suggest keywords with high complementary relevance based on concurrence analysis which cannot support competitive keyword advertising. This paper proposes a notion of substitute relevance as well as the corresponding definition of the substitute keyword. Moreover, a novel substitute keyword suggestion method named SKS is designed to help advertisers find more appropriately competitive keywords. Examples and experiments demonstrate the efficiency and effectiveness of the proposed method.
