A real-time warehouse operations planning system for small batch replenishment problems in production environment

A factory consists of numerous production workstations, multiple production lines and many production floors. Due to the characteristics of just-in-time and make-to-order mode manufacturing, small batches of production materials are required for production lines within a short period of time in order to facilitate daily production operations. In this paper, a real-time warehouse operation planning system (R-WOPS) for solving small batch replenishment problems is described. Through using R-WOPS, real-time production and warehouse operations are monitored by radio frequency identification (RFID) technology, and a genetic algorithm (GA) technique is applied to formulate feasible small batch replenishment solutions. Simulation tests show that R-WOPS generates pick-up and delivery route plans for small batch replenishment orders very efficiently.     

Short term adjustments to production lines

This paper presents a heuristic procedure and the computer software for solving the short term or dynamic production line balancing problem. The procedure is intended for use on periodic basis to determine how many operators should be assigned to each work station on a production line. The objective is to control work in process inventories and minimize idle labor while producing the required amount of final product. The production line is assumed to be balanced in its static state and work elements will not be re-allocated. The computer software is in BASIC, requires very little main core storage and can be readily adapted to run on micro and mini computers.

Agility and production flow layouts: An analytical decision analysis

The term ‘agile manufacturing’ has referred to operational aspects of a manufacturing company concerning their ability to produce customized products at mass production prices and with short lead times. A core issue faced within agile manufacturing is the need for appropriate and supporting production and operations systems. Many design dimensions of agility and agile manufacturing exist. To help attain this goal for integrating the many design dimensions, operations infrastructure and capacity must be carefully planned to manage production flow, and thus production layout planning takes on an increasingly important role. Given the importance of these dimensions in response to agility, this paper seeks to make a contribution by providing insights into a decision aid for evaluating production flow layouts that support and enhance the agile manufacture of products. Layout design has a significant impact on the performance of a manufacturing or service industry system and has been an active research area for many decades. Strategic evaluation of production layouts requires consideration of both qualitative and quantitative factors (managerial, organizational, and technical). This paper makes use of the Analytical Network Process (ANP) which captures interdependencies among different criteria, sub-criteria and dimensions, an evident characteristic of production flow layouts in complex agile manufacturing environments. An application case study exemplifying the practical usefulness of this type of model describes how management, after implementation of the model, made a mid-course correction related to the production layout initially selected.     

Predictive models with endogenous variables for quality control in customized scenarios affected by multiple setups

The crescent demand for customized products has challenged industries with reduced lot sizes. As a result, frequent product model changing and short series of observable variables decreased the performance of many traditional tools used in process control. This paper proposes the use of endogenous variables in predictive models aimed at overcoming the multiple setup and short production runs problems found in customized manufacturing systems. The endogenous variables describe the type/model of manufactured products, while the response variable predicts a product quality characteristic. Three robust predictive models, ARIMA, structural model with stochastic parameters fitted by Kalman filter, and Partial Least Squares (PLS) regression, are tested in univariate time series relying on endogenous variables. The PLS modeling yielded better predictions in real manufacturing data, while the structural model led to more robust results in simulated data.

Game design education: integrating computation and culture

Game studies, as a humanistic discipline, has no defined limits to its coverage, no single methodology, and no clear historical boundary. In short, the creation of a curriculum around games is an emerging practice in which research and education, theory and practice, art and commerce, and existing disciplinary boundaries all continue changing in challenging and unpredictable ways. Although many universities focus their digital media curricula on game production and game studies, Georgia Tech's commitment to humanistic frameworks connect this emerging environment to longer traditions of human culture by emphasizing research into the expressive potential of games.
