Ready-mix concrete delivery problem (RMCDP), a specific version of the vehicle routing problem (VRP), is a relevant supply-chain engineering task for construction management with various formulations and solving methods. This problem can range from a simple scenario involving one source, one material and one destination to a more challenging and complex case involving multiple sources, multiple materials and multiple destinations. This paper presents an Internet of Things (IoT)-supported active building information modeling (BIM) system for optimized multi-project ready-mix concrete (RMC) delivery.

The presented system is BIM-based, IoT supported, dynamic and automatic input/output exchange to provide an optimal delivery program for multi-project ready-mix-concrete problem. The input parameters are extracted as real-time map-supported IoT data and transferred to the system via an application programming interface (API) into a mixed-integer linear programming (MILP) optimization model developed to perform the optimization. The obtained optimization results are further integrated into BIM by conventional project management tools. To demonstrate the features of the suggested system, an RMCDP example was applied to solve that included four building sites, seven eligible concrete plants and three necessary RMC mixtures.

The system provides the optimum delivery schedule for multiple RMCs to multiple construction sites, as well as the optimum RMC quantities to be delivered, the quantities from each concrete plant that must be supplied, the best delivery routes, the optimum execution times for each construction site, and the total minimal costs, while also assuring the dynamic transfer of the optimized results back into the portfolio of multiple BIM projects. The system can generate as many solutions as needed by updating the real-time input parameters in terms of change of the routes, unit prices and availability of concrete plants.

The suggested system allows dynamic adjustments during the optimization process, andis adaptable to changes in input data also considering the real-time input data. The system is based on spreadsheets, which are widely used and common tool that most stakeholders already utilize daily, while also providing the possibility to apply a more specialized tool. Based on this, the RMCDP can be solved using both conventional and advanced optimization software, enabling the system to handle even large-scale tasks as necessary.

This study aims to describe the fundamentals of teaching risk management in a classroom setting, with an emphasis on the learning interface between higher education and the workplace environment for business management students.

The study reviews literature that uses spreadsheets to visualize and model risk and uncertainty. Using six distinct case-based activities (CBAs), the study illustrates the practical applications of software like Palisade @RISK in risk management education. It helps to close the gap between theory and practice. The software assists in estimating the likelihood of a risk event and the impact or repercussions it will have if it occurs. This technique of risk analysis makes it possible to identify the risks that need the most active control.

@RISK can be used to create models that produce results to demonstrate every potential scenario outcome. When faced with a choice or analysis that involves uncertainty, @RISK can be utilized to enhance the perspective of what the future might contain.

The insights from this study can be used to develop critical thinking, independent thinking, problem-solving and other important skills in learners. Further, educators can apply Bloom’s taxonomy and the problem-solving taxonomy to help students make informed decisions in risky situations.

Efforts to implement supplier selection and order allocation (SSOA) approaches in small and medium-sized enterprises (SMEs) are quite restricted due to the lack of affordable and simple-to-use strategies. Although there is a huge amount of literature on SSOA techniques, very few studies have attempted to address the issues faced by SMEs and develop strategies from their point of view. The purpose of this study is to provide an effective, practical, and time-tested integrated SSOA framework for evaluating the performance of suppliers and allocating orders to them that can improve the efficiency and competitiveness of SMEs.

This study was conducted in two stages. First, an integrated supplier selection approach was designed, which consists of the analytic hierarchy process and newly developed measurement alternatives and ranking using compromise solution to evaluate supplier performance and rank them. Second, the Wagner-Whitin algorithm is used to determine optimal order quantities and optimize inventory carrying and ordering costs. The joint impact of quantity discounts is also evaluated at the end.

Insights derived from the case study proved that the proposed approach is capable of assisting purchase managers in the SSOA decision-making process. In addition, this case study resulted in 10.89% total cost savings and fewer stock-out situations.

Criteria selected in this study are based on the advice of the managers in the selected manufacturing organizations. So the methods applied are limited to manufacturing SMEs. There were some aspects of the supplier selection process that this study could not explore. The development of an effective, reliable supplier selection procedure is a continuous process and it is indeed certainly possible that there are other aspects of supplier selection that are more crucial but are not considered in the proposed approach.

Purchase managers working in SMEs will be the primary beneficiaries of the developed approach. The suggested integrated approach can make a strategic difference in the working of SMEs.

A practical SSOA framework is developed for professionals working in SMEs. This approach will help SMEs to manage their operations effectively.

Canada is a member state in the United Nations. In 2015, Canada adopted the 2030 Agenda for Sustainable Development. It is a global initiative that envisions a world where member states will improve economically, socially, and environmentally by attaining 17 Sustainable Development Goals set by the United Nations. This chapter focuses on Sustainable Development Goal 4: Quality Education. A review of Canada's national strategy for mechanizing realization of Goal 4, a snapshot of Canada's midpoint progress, and recommendations for next steps and future considerations are presented.

The aim of this study was to identify interventions for and mechanisms of the digital transformation of purchasing and supply management (PSM) processes. The digital transformation of tactical and operational PSM processes has often progressed slowly despite the solid knowledge of advanced technologies.

This study used a qualitative exploratory approach based on 14 interviews with PSM executives from firms that are continuously working toward using advanced technologies in their PSM processes but have not yet gained full strategic benefits from digital transformation.

This study formulates five propositions regarding interventions and mechanisms that can positively influence the digital transformation of PSM processes. The main intervention in this regard is the renewal of data infrastructure, including platforms. PSM-related data should meet needs from both tactical and operational viewpoints. When applications serve as a source of data, they support digital transformation. Mechanisms such as supplier measurement and process improvement are outcomes of the digital transformation of PSM processes.

This study highlights the importance of common data sets for tactical and operational purchasing. These purchasing data should be owned and served by a cross-functional team. To create this interoperability, a firm needs global governance of open standards.

This study makes a theoretical contribution to the discussion of what kind of interventions positively influence on the digital transformation of PSM processes. Specifically, this study explains the integration needs of data and applications.

In the current manuscript, the authors examine the Belleville spring with the variable thickness. The thickness is assumed to be variable along the meridional and parallel coordinates of conical coordinate system. The calculation of the Belleville springs includes the cases of the free gliding edges and the edges on cylindric curbs, which constrain the radial movement. The equations developed here are based on common assumptions and are simple enough to be applied to the industrial calculations.

In the current manuscript, the authors examine the Belleville spring with the variable thickness. The calculation of the Belleville springs investigates the free gliding edges and the edges on cylindric curbs with the constrained radial movement. The equations developed here are based on common assumptions and are simple enough to be applied to the industrial calculations.

The developed equations demonstrate that the shift of the inversion point to the inside edge does not influence the bending of the cone. On the contrary, the character of the extensional deformation (circumferential strain) of the middle surface alternates significantly. The extension of the middle surface of free gliding spring occurs outside the inversion. The middle surface of the free gliding spring squeezes inside the inversion point. Contrarily, the complete middle surface of the disk spring on the cylindric curb extends. This behavior influences considerably the function of the spring.

A slotted disk spring consists of two segments: a disk segment and a number of lever arm segments. Currently, the calculation of slotted disk spring is based on the SAE formula (SAE, 1996). This formula is limited to a straight slotted disk spring with freely gliding inner and outer edges.

The equations developed here are based on common assumptions and are simple enough to be applied to the industrial calculations. The developed method is applicable for disk springs with radially constrained edges. The vertical displacements of a disk spring result from an axial load uniformly distributed on inner and outer edges. The method could be directly applied for calculation of slotted disk springs.

The nonlinear governing equations for the of Belleville spring centres were derived. The equations describe the deformation and stresses of thin and moderately thick washers. The variation method is applicable for the disc springs with free gliding and rigidly constrained edges. The developed method is applicable for Belleville spring with radially constrained edges. The vertical displacements of a disc spring result from an axial load uniformly distributed on inner and outer edges.

Given the implementation of a new Certified Public Accountant (CPA) licensure exam and the CPA Evolution Model Curriculum, accounting educators must integrate more advanced skills in their coursework. We illustrate how a commonly-used project in accounting classes, which teaches technical accounting content, can address skills and competencies identified by the Pathways Commission and the American Institute of Certified Public Accountants (AICPA) and, as a result, enhance skills all business school graduates need in the workplace.

We incorporate a financial statement analysis research project under a group work format in three levels of financial accounting classes. Using both quantitative and qualitative analysis, we evaluate changes in student perceptions of skills and competencies important for business graduates.

We find students perceive improvement in critical thinking, problem-solving, the ability to work with other people, their understanding of the course material, and data analysis abilities after completion of the project. We also find statistically significant increases pre-to post-project in student perceptions of their knowledge, confidence, competence, and enthusiasm with respect to accounting material.

We provide an example of how educators can align a commonly-used project with the CPA Evolution Model Curriculum, yet still meet the needs of non-accounting majors and prepare all students for future business careers. Group work has been studied and similar financial statement analysis projects have been implemented in the classroom for years. We contribute by not only extending and updating this research, but also by re-evaluating a project to determine whether it meets the shifting needs of a rapidly changing profession. By doing so, we answer recent researchers’ call for research in higher education that addresses employability and workplace skills.

Despite the ever-increasing importance of cultivating information, communication and technology literacy skills among college students, they have yet to be related to comprehensive measuring instruments. A glance at the empirical literature reveals that most pertinent scales have been confined to measuring Internet literacy skills, whereas educators in the 21st century advocate an inclusive conceptualization of ICT literacy. Such a comprehensive conceptualization embodies technical, critical, cognitive and emotional competencies. Additionally, more empirical evidence is needed to indicate gaps in testing measurement invariance of ICT literacy scales across genders or cultures. To that end, the current study aims to adapt and cross-validate an ICT literacy self-efficacy scale across gender by testing the measurement invariance using a multiple-sampling confirmatory factor analysis (MCFA). Furthermore, the current study aims to verify the ICT literacy self-efficacy scale's psychometric properties to establish its construct validity and understand the scale's underlying factorial structure.

The current study has administered the scale to a cross-sectional sample of 3560 undergraduate students enrolled in six universities in the Sultanate of Oman.

The results have revealed that the ICT literacy self-efficacy exhibits satisfactory indices of construct validity. On the other hand, the results of MCFA demonstrate that the differences in the goodness of fit indices between the nested models and the baseline model were below the cut-off criterion of 0.01, indicating invariance. Therefore, the scale has proved to be amenable for comparing genders on their ICT literacy self-efficacy using an one-way multivariate analysis of variance.

The study has several implications for research and pedagogical practices. The study provides empirical evidence for establishing ICT literacy self-efficacy as a distinct high-domain construct of task-specific self-efficacy beliefs.

After completion of this case study, students should be able to reflect on the concept of creating shared value and then determine whether Shesha Geza can be referred to as a shared value company and, if so, what level of shared value it demonstrates. They will be able to subjectively and objectively understand the possible meaning of when a social enterprise embarks on a strategy to scale the organisation; clarity of construct will enable managers to better plan and successfully implement scalability goals. They will also be able to recognise, once scalability goals are better understood and planned, that there are a multitude of intra-organisational levers and drivers that may contribute to the organisation’s ability to scale its operations, which are related to specific internal organisational capabilities of social enterprise companies. In addition, there are situational factors that may affect the business either positively or negatively in relation to the scalability success of which a social entrepreneur should be aware.

In April 2021, Dean Boniface and his brother, Roger, had just signed off a new informational video for their Shesha Geza innovation, a low-cost hand-washing station designed for use at commuter hubs and high-traffic areas across the African continent. The unit used diluted chlorine instead of alcohol-based sanitisers to ensure a more expedient and sustainable solution, one better suited to Africa’s logistical challenges. Boniface, the co-founder of Vue Architects, had conceptualised the idea of the hand-washing hub during South African Government’s enforced COVID-19 lockdown from 27 March 2020 to 1 May 2020. Shesha Geza’s speed to market was a key contributor to its successful response in solving a critical social need. Throughout 2020, Boniface and his team built successful partnerships and secured an impressive order pipeline within a short span. Export opportunities across Africa, installations and maintenance of a sizable number of units across South Africa and the development of a behavioural change programme aimed at hygiene in schools kept the momentum going in the business. However, a year into the business and the future sustainability of a crisis–response enterprise and the ability of a shared value enterprise to scale were playing on Boniface’s mind. He was worried about the future of the small resource-constrained business. Holding onto the mental map of everything the team had learned over the past year, Boniface was confident about one thing: “All the programmes we build around Shesha Geza are value-adds to our current business. Hand hygiene will not diminish after COVID-19; it will continue to be an important social issue across the African continent.”

This case is intended for discussion in post-graduate-level courses such as an MBA and in postgraduate courses focused on business model innovation or on creating shared value. This case is suitable for use in the environment of business courses in relation to environmental situational factors that may affect the ability to scale social enterprises or strategic implementation courses, considering the still pervasive challenge of scaling increasingly important social impact enterprises.
