The Practice of Structural Equation Modeling

The aim of this chapter is to act as a point of reference for researchers, especially new users, who would like to use structural equation modeling (SEM) to perform business analytics. SEM is a multipurpose statistical modeling technique that can be applied in various business disciplines and is a useful tool to conduct business analytics. This chapter explains some common terminologies in the SEM literature and states general steps of performing SEM analysis along with an integration of the wide range of views and empirical findings on the topic. The chapter discusses the assumptions of SEM analysis, followed by a three-stage process of conducting, which includes assumptions, specification, evaluation, and modifications.

Stock Counting System Using PDA

In this work, a development of stock counting system using PDA is presented. The design and development issues are studied for the case of a superstore in Thailand. The stock counting is a tedious work in a department store. Employees need to physically walk down the shelves and count the amount of items each day. The amount of items is compared to the amount in the system to check for the loss of items every day. For a large-size department store, many employees need to spend lots of time to perform the tasks. Introducing the use of PDA together with the barcodes of the products will help automate the process, save time, and reduce the errors for checking the stock counts. In this paper, the design of system presents in the aspect of 1) the PDA software client and server sides 2) wireless access point installation costs and plans. After the development, the system is employed. Its efficiency is compared to the manual counting and the user satisfactory is evaluated.
