Layout decision is an important issue in electronics manufacturing process. A good layout with better arrangement of assembly machines will increase overall efficiency and throughput. It is not uncommon that many industrial companies in Hong Kong do not use systematic layout planning methods for their layout decisions. This paper aims at developing a simulation model to analyze the best layout decision for an electronics manufacturing company. Finally, a simplified fuzzy PERT network framework is proposed to model a Surface Mount Technology (SMT) production line for calculating the fuzzy throughput time of the SMT line under fuzzy processing parameters.

A new set of Walsh functions is defined in terms of the split-matrix ordering. The intrinsic properties of the functions are analyzed. The relationship and the associated conversion rules between the newly defined functions and other typical Walsh functions are discussed. It is shown that the proposed Walsh functions provide a straighforward and efficient algorithm for fast Discrete Walsh Transformation.

Abstract. The Hankel transformation was extended by Zemanian to certain generalized functions of slow growth through a generalization of Parseval's equation as (1) (h"f, 9) = (/, K where Jov.it is the testing function space which contains the kernel function, yf^yJit(xy) ■ A transformation was defined directly as the application of a generalized function to the kernel function, i.e., for feJp,(hitf)(y) = (f(x),Vxyjfl(xy)).In this paper, we extend definition (2) to a larger space of generalized functions. We first introduce the test function space Ma,ii which contains the kernel function and show that Hf, c Ma,p¡ C Ja,it ■ We then form the countable union space M^ = \J%X May,n whose dual M^ has J^ as a subspace. Our main result is an inversion theorem stated as follows.
