the basic type of assembly line balancing (alb) problem is the allocation of work elements to a set of production work stations considering cycle time, precedence constraints, and assembly diagram to achieve predefined performance criteria such as line efficiency and smoothness index. in this paper, a mixed integer programming model for solving multiple product alb problems with processing time...

When building a cross-border transmission line (a so-called interconnector) as a for-profit (merchant) project, where the regulator has required that capacity allocation be done non-discriminatorily by explicit auction, the identity of the investor can affect the profitability of the interconnector project and, once operational, the resulting allocation of its capacity. Specifically, when the i...

This paper presents a multi-objective Particle Swarm Optimization (PSO) algorithm for worker assignment and mixed-model assembly line balancing problem when task times depend on the worker’s skill level. The objectives of this model are minimization of the number of stations (equivalent to the maximization of the weighted line efficiency), minimization of the weighted smoothness index and minim...

This paper proposes a new mathematical model to describe the distribution of the occurrence of errors in data transmission on telephone lines. We suggest: a) that the statistics of telephone errors can be described in terms of an error probability depending solely on the time elapsed since the last occurrence of an error; b) that the distribution of inter-error intervals can be well approximate...

In this paper we study two-person bargaining problems represented by a space of alternatives, a status quo point, and the agents’ preference relations on the alternatives. The notion of a family of increasing sets is introduced, which reflects a particular way of gradually expanding the set of alternatives. For any given family of increasing sets, we present a solution which is Pareto optimal a...

Abstract Straight line is the most basic element of graphics, and it is of great significance to study fast algorithm of line generating. On the basis of Bresenham algorithm, this paper considers and takes full advantage of the relativity between adjacent pixels in the line, and can generate all the pixels in a pixel line every time. The new algorithm based on pixel line can guarantee the line ...

The scope of a wholesale market may, in addition to demandand supply-side substitution at the wholesale level, also be determined by substitution patterns at the retail level. Considering wholesale broadband access markets, it is argued that each of these forces can be strong enough to render a 5-10% price increase by a hypothetical monopolist at the wholesale level unprofitable and thus may le...

In this paper, the design of three stage hybrid architecture for controlling and preventing certain disturbances caused in transmission lines is studied. The transmission lines of modern power systems are equipped with WSN (Wireless Sensor Network). Since WSNs are capable of cost efficient monitoring over a wide range of geographical areas. Consequently monitoring of mechanical parameters of tr...
