This study presents a new method for modeling an adaptive neuro-fuzzy inference system (ANFIS) based on vibration for predicting surface roughness in the CNC turning process. The input parameters of the model are insert nose radius, cutting speed, feed rate, depth of cut and vibration amplitude, which determine the output parameter of the surface roughness. A Gauss type membership function was ...

Until now, decision under uncertainty and multicriteria decision making have been investigated separately and almost independently, although there is a close link between both fields. Decision theory is also closely related to measurement theory. Besides, it is well known that additive representations in decision making are not sufficient to avoid paradoxes such as Ellsberg’s paradox. Therefore...

nowadays, the customer's credit assessment is one of most important challenges for managers in decision making. especially in the current situation which the number scam has increased and outstanding claims of business company is increasing. on the other hand decision making about customers and their credit is based on expert judgment and also the customer information is often uncertain, a...

This paper describes the implementation of an integrated monitoring system for a CNC machine tool and its machining processes such as drilling, milling, turning and grinding. The monitoring system uses a variety of sensors such as force, torque, vibration, acoustic emission, and temperature to monitor the machining processes and the physical condition of the machine tool. The major aim is to im...

In this paper, we propose arrow decision logic (ADL), which combines the main features of decision logic and arrow logic. Decision logic represents and reasons about knowledge extracted from decision tables based on rough set theory, while arrow logic is the basic modal logic of arrows. The semantic models of ADL are pairwise comparison tables, which are useful in rough set-based multicriteria ...

CollabCAD is an indigenous 3D CAD/CAM software system for collaborative design and development of Industrial Designs for strategic use. This work is for CAM module of the indigenous software, in which the development of post-processor is the task that is accomplished. The CAD model is created in CollabCAD and the required tool path was produced in a generic format known as Cutter Location (CL) ...

Industrial Automation is a broad field among other engineering disciplines. The major activities of Automation stem from manufacturing industries and include cycle time improvement, productivity improvement, cost reduction, efficiency improvement, materials handling, analyze and improve the work methods, to eliminate waste and proper allocation and utilization of resources. Automation in a manu...

A novel approach, based upon fuzzy logic and frames, for the creation of fuzzy expert shell is being proposed in this paper. The fuzzy logic effectively deals with the type of communication normally used by humans, whereas the frames have been used to store the correlated information in the form of a block. This shell uses a local inference mechanism within the frame with the help of a multicri...

In this work, multicriteria decision making objective for flow shop scheduling with sequence dependent set up time and due dates have been developed. Multicriteria decision making objective includes total tardiness, total earliness and makespan simultaneously which is very effective decision making for scheduling jobs in modern manufacturing environment. As problem of flow shop scheduling is NP...

The significant cargo volumes transferred by sea, in combination with the increased technological and operational requirements that international competition imposes, lead to the continuous upgrade of infrastructure and equipment of modern port terminals. Within this framework, a number of new technologies for the transhipment of unitised cargo have been developed and are available in the marke...
