Revenues and profits from short life cycle products will depend upon careful formulation and execution of production plans in response to demands in the marketplace. This research contributes to the development of the production and inventory build-up strategies for short life cycle products under different demand-supply scenarios. A modified Bass diffusion model is used to characterise the product demand pattern with consideration of demand-sales interaction. We develop cost models based on production costs, inventory carrying costs, backlog costs, and cost of lost sales for a number of different production scenarios. The optimal production rate is obtained by minimising the total cost. We also investigate the benefit of an initial build-up of inventory before the product's sales period starts. © 2013 Inderscience Enterprises Ltd.

A step-based tutoring system for linear circuit analysis is being developed with the capabilities to automatically generate circuit problems with specified characteristics, including randomly generated topologies and element values. The system further generates fully-worked, error-free solutions using the methods typically taught in such classes, and accepts a rich variety of student input such as equations, matrix equations, numerical and multiple-choice answers, re-drawn circuit diagrams, and sketches of waveforms. A randomized, controlled study was conducted using paid student volunteers to compare the effectiveness of two of our tutorials in comparison to working conventional textbook-based problems. The average learning gain was only 3/100 points for the textbook users, but 29/100 points, about 10 times higher, for the tutorial users. The effect size on the post-test scores was 1.21 pooled standard deviations (Cohen d-value) and was statistically significant. A motivational survey administered to these students yielded a 0.53 point higher rating for the software than for the textbook (on a 1-5 scale). The system is being used in Spring 2013 by over 340 students in EEE 202 at Arizona State and two community colleges. About 99% of these students rated the system as “very helpful” or “somewhat helpful”.

The current state of the world economy has made Software-As-A-Service (SaaS) an appealing concept for organizations with a small budget for IT infrastructure investment. In a SaaS setup, companies subscribe software applications on a pay-per-use system from external service providers over the internet. However, these companies are looking for a decision framework that can be used to prioritize business software applications for SaaS migration. This paper attempts to fill in this gap by proposing a hybrid methodology which is composed of a total system life cycle (SLC) cost analysis for cost estimation and the analytic network process (ANP) for prioritization. Real test case data is used to validate the decision making capability of the framework. Sensitivity analysis was done to determine the robustness of the recommendations using Monte Carlo simulation. Results show that the proposed methodology could aid managers prioritizes software application projects for SaaS migration. © 2012 Newswood Limited. All rights reserved.

The creation of tools, techniques and methodologies to support the manipulation of large data sets has been receiving special attention of both scientific and industrial communities, in order to discover new ways of dealing with the underlying information, including learning purposes, identification of patterns, decision making support, amongst others. However, making use of computing resources to enhance awareness and understanding of software information and the software itself is still a challenge in software/systems engineering, since it involves the identification of suitable mechanisms, adequate abstractions, and studies on stimulation of the human perceptive and cognitive abilities. This paper presents some of the challenges in this context, based on current trends of software development lifecycle, program comprehension, and software engineering education. At the end, a special focus is given on ongoing research on using and improving current mechanisms for supporting software reuse practices and software comprehension in general. © 2012 IEEE.

Software-as-a-Service (SaaS) applications are currently an appealing concept for organizations with a small budget for IT infrastructure investment. By definition, in a SaaS setup, companies subscribe software applications on a pay-per-use system from external service providers over the internet. However, managers are looking for a decision framework that can be used to prioritize business software applications for migration into a SaaS environment. This paper attempts to fill in this gap by proposing a hybrid methodology which is composed of a total system life cycle (SLC) cost analysis for cost estimation and the analytic network process (ANP) for prioritization. Real test case data is used to validate the decision making capability of the framework. Sensitivity analysis was done to determine the robustness of the recommendations using Monte Carlo simulation.

In response to our nation's cry for more engineers, this paper describes how a major university has leveraged four NSF program grants to produce a highly successful program focused on retention, graduation, and graduate degrees. One of the programs is for lower division students, one is for upper division transfer students, one is for non-transfer upper division students and graduate students that have come up through the system, and one is for upper division students who come from five selected non-metropolitan community colleges in Arizona. The last program ties everything all together with a Transfer Student Center, a place for the S-STEM Academic Scholarship Success Class to meet, a place to host potential transfer students, and a place for transfer students to study and network. An emphasis of all of these programs is the encouragement and support of female and underrepresented minority students and students with unmet financial need. These programs have attained a 90-95% retention rate. For upper division transfer students not in the program, the graduation rate is about 70% for males and 64% for females. The transfer GPA shock was shown to be negligent for new program transfer students, compared with a half grade point drop for new upper division transfer students not in the program. Most importantly, during the past three years over 50% of the graduated scholarship students have gone right on to graduate school full-time. Seventy percent of the transfer students who did not intend to go to graduate school when they matriculated to Arizona State University, but who have now chosen to go on to graduate school, have reported that this program was a major influence in this decision change. Several of the students are now in PhD programs preparing to become professors. Even though parts of this program have been in existence for nearly 10 years, this is a continual work in progress as we strive for more excellence. This paper highlights the successes of being abl

The purpose of this investigation was to develop the STEM Active Listening Skills Assessment (STEM-ALSA), a conceptually grounded instrument designed to measure four components of active listening, a key element of communication in an academic setting. The STEM-ALSA is comprised of three unique scales that measure a person's knowledge (12 items), ability to apply (25 items), and self-efficacy (5 items) with respect to active listening. Two pilot studies were conducted with N = 99 upper level undergraduate students enrolled in STEM disciplines to develop and evaluate the instrument. Results of an exploratory factor analysis identified both a unidimensional factor structure for each of the three scales and total scores with adequate internal consistency reliability estimates. The STEM-ALSA provides a mechanism for measuring active listening skills among students in STEM.
