Abstract Hierarchical organizations have to build the right human resource (HR) composition to fulfill their operational and strategic needs. One of the largest hierarchical organizations that face this challenge is the military organization. To tackle this challenge, managers rely on military HR planning that consists of strategic planning and operational planning. The general practice of focusing on the strategic planning then dealing with the operational planning could lead to an undesired manpower composition. Therefore, we propose an approach that allows simultaneous HR planning for both strategic and operational levels. Such simultaneous planning ensures building an adequate plan that considers the different aspects of personnel. We employ a flow network model to represent the military human resource system. To find an adequate solution that, we use mixed integer goal programming.

Abstract The paper presents an organizing framework for directly incorporating United States Department of Defense (DoD) joint operational concepts into early-stage engineering management and system design. It translates operational level guidance from DoD Joint Publications to a concise Operational Mission Architecture Framework (OMAF) that can be used as a starting point for engineering management efforts. The OMAF is used to orient the development of systems architecture products per Department of Defense Architecture Framework (DoDAF) standards. Resultantly, the OMAF serves as a bridging mechanism between the language and terminology employed in the joint operational community and the engineering management community.

Abstract Increments in economic efficiency resulting from the application of standards generate economic benefits for both producers and consumers. As a result, it is of the utmost importance for organizations to be aware of the benefits that standards bring to their operations. This paper deals with specific categories of standardization effects that organizations can achieve in the processes of formal standardization. The goal was to rank organizations by size, based on the effects that they can gain by getting involved in formal standardization. The data gathered from a survey of experts from the Institute for Standardization of Serbia form the basis of our multicriteria analysis of standardization indicators for micro, small, medium-sized, and large organizations. The final ranking for determining the achievement of standardization effects in different-sized organizations was performed using the PROMETHEE-GAIA method. Our analysis showed that micro organizations were the best performers since they are more flexible than the other size categories of organizations. In contrast, the other types of organizations have lower significant preferences concerning all the criteria. Finally, one of the conclusions is that all observed organizations have the potential to achieve the effects of standardization, although they may differ.

Abstract This study explores empirically the underlying mechanism through which organizational flexibility affects the performance of its project portfolio, using innovation capability as a mediator, and examines the moderating role of environmental uncertainty in the relationship between organizational flexibility and innovation capability. Data collected from 201 firms were analyzed using partial least squares structural equation modeling with SmartPLS software. The study shows that organizational flexibility positively affects innovation capability and that innovation capability has a positive impact on project portfolio performance. Further, innovation capability positively mediates the relationship between organizational flexibility and its project portfolio’s performance. The adverse moderating effect of environmental uncertainty on the relationship between flexibility and innovation capability also found. The study contributes to innovation theory by using quantitative data to address the role of flexibility in improving innovation capability and the performance of project portfolios and provides a framework that managers can use to enhance the performance.

Abstract The United States inland waterway transportation system is comprised of 12,000 miles of navigable waterways that connect and move freight between 38 states and the global supply chain. When investing in inland waterway infrastructure, engineering managers should aim to maximize all benefits associated with the investment, including flood protection, water supply, hydropower generation, recreation, and environmental impact benefits. In this article, we formulate an initial qualitative value model for inland waterway infrastructure investment decisions, based on a value-focused thinking approach that enables engineering managers to holistically evaluate project investment alternatives. For circumstances involving limited resources, a portfolio optimization model is formulated to maximize the total value associated with project investments, while considering budget and minimally acceptable benefit constraints. To demonstrate an application of our approach, we present a case study based on the McClellan Kerr Arkansas River Navigation System.

Abstract This paper examines the variation in career plans among U.S. senior year mechanical engineering undergraduates. The extent to which candidates persist from engineering school into engineering careers attracts attention from hiring managers, educators, and policymakers concerned with the future of the engineering workforce. Prior research has identified patterns of systemic variation in engineering students’ persistence, finding that particular student subsets exhibit lower likelihoods of pursuing conventionally categorized engineering jobs after graduation compared to others. These groups have included students from underrepresented demographics and those with particular key skills profiles. Based on survey data from a sample of 1,061 mechanical engineering seniors across nine universities, we first constructed an occupational sorting model that replicates previously reported relationships between student-specific factors and students’ intentions to work in engineering. We then expanded this model into a new multinomial outcomes model that examines the unique sets of factors associated with specific categories of occupational intentions from an array of engineering and non-engineering options. We find factors such as internship experiences, risk aversion, mathematics enjoyment, strength of professional identity, leadership aspirations, perceptions of creative opportunities, and salary expectations to be significantly associated, in unique combinations, with various types of occupational intentions. We conclude by discussing how knowledge of factors salient to students’ occupational sorting tendencies can help engineering managers refine approaches for recruitment and job formulation, so as to potentially broaden the attractiveness of engineering jobs across the candidate pool and to improve candidate-job matching.

Abstract As modern engineered systems become ever more connected and interdependent there is an increasing need to evaluate their complexity. However, evaluating system complexity is challenging due to the complicated conceptual landscape of competing definitions of the term complexity itself, and the range of perspectives that can be taken on what constitutes the System of Interest. This paper attempts to overcome these hurdles through introducing a Complexity Register with which to build and record a shared understanding of system complexity for key stakeholders. In order to overcome current challenges in evaluating the complexity of an engineering system, the Complexity Register encourages personnel to adopt a broad range of perspectives on the potential issues, impacts, and mitigations to manage system complexity. The formulation of the Complexity Register is informed by design principles derived from a case study analysis of a system complexity evaluation tool. The Complexity Register should enable more effective shared understanding by encouraging collaboration that makes explicit the multiple viewpoints taken when evaluating system complexity and promoting continued reevaluation throughout a system or project lifecycle.

Abstract Supply Chain Performance (SCP) is a critical issue in most industries. Organizations expect to enhance their SCP because it allows better competitiveness through minimizing useless resources activities, unsatisfactory delivery times, noncompliant quality, overproduction, etc. In this context, this paper provides an overview of the methods in use in Supply Chain Performance Measurement (SCPM) and investigates the most used methods for data collection, approaches, and data analysis techniques in order to measure SCP. This study was based on 180 of 682 related articles, published from 2008 to 2019, which were collected from the Crossref and Sciencedirect databases. Articles were reviewed in order to update methods and techniques which are the most used to define and analyze this performance, both in academic research or industrial case studies. Findings of this work can be very helpful to researchers and practitioners to know similitude and difference of each method, approach and tool exploited in the field of SCPM, in their particular area of activity.

Abstract With 212 locations serving a geographical area three times the size of the state of Texas, our international client has been experiencing unexpected failures in his portfolio of thousands of refrigeration units, resulting in an associated loss of $1.4 million. These losses have been attributed to lapses in food quality caused by improper refrigeration, and the adopted reactive maintenance strategy of the refrigeration units. To assist our client in complying with the cold-chain regulations of food safety and mitigate such losses, the agent-based simulation was used to model and assess the viability of two distinct massively populated Internet of Things (IoT) alternatives. The first (alternative A) involves monitoring the availability of each of the refrigeration units and signaling for the initiation of repair processes and food removal from failed units when the cooling temperature differs from a specified threshold and a more sophisticated and expensive alternative B that involves the adoption of the added capability of a condition-based predictive maintenance strategy to reduce unplanned downtime and mitigate or eliminate the causes of failure. Using historical data, a simulation of the current operations was first modeled, validated, and then augmented with capabilities to address the operational characteristics of the proposed IoT implementations. Results of financial analysis results including the probabilistic risk analyses, that account for the variations and the probability distributions of the assumption parameters, showed alternative A to be superior, with a mean net present value (NPV) of $416,703, and a modified IRR of about 18.77% exceeding the project cost of capital of 12.80% with complete certainty. The client was also advised that a 30% reduction in the acquisition cost would make investment B as viable as investment A.
