To do so, wider objectives are included; which naturally leads to more complex combinatorial optimization problems. This paper introduces a new mathematical model to solve the routing problem of a fleet of reefers that extends the typical model by considering the energy consumption of the refrigeration unit. The results illustrate that considering the effect of refrigeration as a new variant of the routing problem can achieve between 3.8% to 11.1% energy saving.

tools and the plant floor. Simulation can be used to generate production
schedules on an ongoing basis in a way that does not violate constraints related
to the limited availability. In this paper, the process of tablet manufacturing in a
pharmaceutical production plant is studied, first the full process is described
and mapped, and then a process simulation is run. Based on the simulation
results, statistical analysis is performed; the data is fitted by using regression
analysis. Design of experiment (DOE) analysis is performed on the process to
try many different combinations of resource levels automatically, and finally
analysis of variance (ANOVA) is performed to select infeasible products that
can be excluded from future production plans, this will have a positive effect on
the return on investment for the organisation.

With the recent rise of smart systems (e.g. Internet of things) and digital platforms (e.g. blockchain), smart contracts are gaining high interest in both business and academia. In this work, a framework for smart contracts was proposed with using reputation as the system currency, and conducts currency mining through fulfilling the physical commitments that are agreed upon.Design/methodology/approachA game theory model is developed to represent the proposed system, and then a system dynamics simulator is used to check the response of the blockchain with different sizes.FindingsThe numerical results showed that the proposed system could identify the takeover attacks and protect the blockchain from being controlled by an outsider.

This external hired company is known as Third Party Logistics (3PL). 3PL selection decision inherently is a multi-criterion problem, sometimes with strategic importance to companies. Management science techniques might be helpful tools for these kinds of decision-making problems. Multi-Criteria Decision-Making (MCDM) techniques are often used to solve 3PL problems. In this paper, different types of MCDM are overviewed, and then a framework for 3PL selection is proposed by using a hybrid two-phase Fuzzy Analytic Hierarchy Process (FAHP) to select the best 3PL company providing the most satisfaction for the criteria determined, and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to evaluate the performance of 3PLs. This integration provides a good methodology to rank 3PLs.

Cargo transportation is one of the most challenging issues in logistics; in this paper, we explore multiple stakeholders’ information environments surrounding containerized cargo transportation by a design thinking approach. Throughout the analysis, the latent problems are summarized in the following two manners: (1) miscommunication with inefficient information flow among multiple stakeholders; and (2) a lack of resource management coordination among service providers. With these two identified problems, the objective of this work is to develop a prototype information and communication technology-based service application for both trucking companies and customers.

It is believed to have the potential for revolutionizing today’s world. Several projects and publications addressed the use of IoT in various applications such as smart cities, smart homes, wearables, smart grids, connected vehicles, and health care. However, few works addressed the potential of using IoT in educational institutions. The technological revolution along with several changes through the past era, including the COVID-19 global pandemic, have made it indispensable to employ innovative learning methods, also, the students will be looking forward to existing in the environment of a smart campus. This study presents a framework to elucidate how IoT can be used to bring a smart and innovative university campus to life in order to improve the efficiency of delivering the daily educational activities. In the context of sustainable development, the social and environmental interactions should be considered to provide a sustainable campus. Also, challenges are investigated and research opportunities are highlighted. This framework can be put in practice in guiding universities to adopt novel visions to improve the performance of their educational activities and student life experience by properly adopting and deploying IoT technologies. These concepts are elaborated based on the case of the innovative campus of the Egypt-Japan University of Science and Technology, which is located in New Borg Elarab, Alexandria, Egypt.

That was the age under the leadership of Muhammad Ali Pasha who ruled Egypt from 1805 to 1848. The paper illustrates how the modern science was introduced into Egypt from Europe. The main research question is: if Egypt started its modernization process in the first part of the 19th century, much earlier than Japan, why eventually Egypt ended up as a developing country, while Japan is now one of the most developed countries in the world? A comparison between the modernization in Egypt during the reign of Muhammad Ali and his successors and in Japan after the Meiji restoration in 1868 may produce some clues.

Hence, it has become very necessary to allocate its resources efficiently and manage it effectively. A sound warehouse management system can contribute to cost reduction and improve customer satisfaction. However, traditional warehouse management system models have become unsuitable and inefficient for today's market requirements. So, companies have started to adopt innovative approaches and technologies to be used for such applications; one of these technologies is the Internet of Things that enables the connection between several physical objects and produces a massive amount of real-time data that can be transferred to useful information that helps in managing and decision making. In this paper, the architecture of this application is illustrated, its potential benefits are overviewed, and a framework for implementing this technology in a warehouse is proposed. This system can help in achieving more control and monitoring on all the operations in the warehouse in real time, increase speed and efficiency, and prevent counterfeiting and inventory shortage. The proposed framework can be taken as a roadmap for enterprises to improve warehouses by using the Internet of Things. Also, the benefits of implementing the proposed framework and its challenges are proposed.

To address this, a design science research methodology was applied for elucidating users' requirements. As empirical evidence, a case study was conducted on the children's book industry to synthesize a knowledge-sharing design application named "StoryWeb". Usability tests were conducted to reconfigure users' feedback and suggestions after two StoryWeb prototypes were developed. This study makes three main contributions. First, it empirically tests individual's or group's creativity and co-creation by a view of knowledge sharing. Second, it methodologically applies a design thinking approach into a knowledge-sharing study. Third, it also practically suggests feasible guidelines for the creativity and innovation research community on which features of storytelling-based applications can be configured.

The objective is to minimise the total costs without violating demand fulfilment policy. A production-inventory-distribution-routing problem of medium size is a combinatorial optimisation problem mostly intractable to solve using exact methods. The main contribution of this work is to introduce valid inequalities for a problem with a single plant, multiple products and multiple heterogeneous vehicles to improve the quality of lower bounds, obtain a good approximation of the convex hull of the polyhedron of the problem and reduce its hypervolume, so that the computation time can be reduced without a significant effect on the quality of the solutions found. The results showed that adding the valid inequalities to the model can improve the percentage gaps for all the tested instances with a significant improvement in the lower bounds from the poor bounds obtained from the linear programming relaxation (up to 98.8% for the dataset of 50 customers and up to 79.7% for the dataset of 100 customers).

This raises many issues and concerns due to the high population and the improper waste management. For the Arab countries, the amount of municipal solid waste generated is about 81.3 million tons per year; less than 20% is adequately treated, and less than 5% is recycled. Another main issue is the transportation and logistics of waste. To address these issues, this chapter adopts ‘reverse logistics’ to explore how to manage waste and increase waste utilization efficiently. The scope of this chapter is Egypt and can be generalized to the Middle East and North Africa (MENA) region. The main interest of this chapter is to understand the role of reverse logistics in waste management and to determine the factors that influence logistics decisions and practices for waste management.

Warehouses are a basic part of the supply chain; they are used to store products and manage the inventory level. A sound warehouse management system can lead to cost reduction and also can improve customer satisfaction. Traditional warehouse management models have become less efficient and unsuitable for today's increasing market requirements. For the past decades, information and communication technology has been used for warehouse management. This paper presents a new approach for warehouse management by utilizing one of the main pillars of Industry 4.0, the Internet of Things. This new technology enables the connection of several objects through collecting real-time data and sharing them; the resulting information can then be used to support automated decision-making. The architecture of this application is illustrated and its potential benefits are overviewed. A framework is proposed to implement this approach in warehousing management, which can help in providing real-time visibility of everything in the warehouse, increasing speed and efficiency, and preventing inventory shortage and counterfeiting. This proposal gives an effective roadmap for enterprises to improve their warehouses by using the Internet of Things.

In this paper, different types of MCDM are overviewed, and then a framework for 3PL selection is proposed by using a hybrid two-phase Fuzzy Analytic Hierarchy Process (FAHP) to select the best 3PL company providing the most satisfaction for the criteria determined, and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to evaluate the performance of 3PLs. This integration provides a good methodology to rank 3PLs.

Hence, it has become very necessary to manage warehouses effectively and allocate their resources efficiently. Warehouse Management Systems (WMSs) have been developed for monitoring, tracking and controlling the warehouse operations, but with the increasing dynamicity of the market, traditional systems have become less efficient and unsuitable for today's market requirements, that is why new technologies have started to emerge to be used for such applications. Internet of Things (IoT) is a promising technology that can be used in the context of Industry 4.0. In this paper, a smart WMS framework based on IoT is proposed; this system helps the warehouse manager to achieve more control and monitoring of the operations in real time. A review of WMS and IoT implementation in warehouses is presented. Also, the blocks and layers of IoT are illustrated. Finally, the benefits and challenges of implementing IoT in the supply chain and the warehouse are discussed.

As with innovation, the business environment is still not well adapted to adopt these concepts. This paper focuses on developing a theoretical business model for organizational sustainability that takes into consideration the environmental, economic, and social issues. An exploratory study was designed for a case study from the Egyptian chemical industry to recognize the relation between innovation and organizational sustainability, and thee willingness to adopt these concepts. The findings of the study provide insights and suggestions for the organization to implement innovation and organizational sustainability.

Another challenge is designing such smart tourism systems while embracing diversified tourists' sustainable values of experience (functional values, social values, emotional values, and epistemic values). In light of these challenges, the overall objective of this work is to design a smart tourism experience-centered system that considers social and technical perspectives. The Socio-Technical Systems theory was adopted as a theoretical foundation, and the Design Science Research methodology was used to develop a smart tourism system and a practical design artifact. A case study from the Japanese tourism context was studied by exploring tourists' sustainable values of experiences and local staffs' behaviors. The main problem was the dysfunctional communication between local service staffs and foreign tourists during the service process. After identifying the problem and the objectives, a relevant smart tourism system was synthesized and tested as a design artifact. The results of the utility test of the proposed artifact showed its effectiveness and efficiency in facilitating the service process and in creating multi-dimensional values of experience.
Supply Chain Management: Applications for manufacturing and service industries, 2016

Vertical collaboration is the integration made through the supply chain of a single organization between different functions. In this chapter, vertical collaboration is explained and a review of related work is presented. In this context, six supply chain management integrated problems are considered; the location routing problem, the inventory location routing problem, the production distribution problem, the inventory routing problem, the production scheduling-vehicle routing problem, and the production inventory-distribution-routing problem. The paper provides a detailed taxonomy based on decision making level (strategic, tactical, and operational), supply chain structure, modeling approach, objectives and decision variables, solution approach, contributions, and applications. The review covers the period from 2008 to 2014 to provide the recent trends in this research area. The production-inventory-distribution-routing problem was selected as a comprehensive representative of vertical collaboration in supply chains. The problem addresses joint optimization of production lot-sizing, inventory management, distribution planning and vehicle routing with the objective of minimizing the total costs of all the included functions and satisfying service levels. Insights and framework are given for this problem with potential research directions to fill the current research gaps.

tools and the plant floor. Simulation can be used to generate production
schedules on an ongoing basis in a way that does not violate constraints related
to the limited availability. In this paper, the process of tablet manufacturing in a
pharmaceutical production plant is studied, first the full process is described
and mapped, and then a process simulation is run. Based on the simulation
results, statistical analysis is performed; the data is fitted by using regression
analysis. Design of experiment (DOE) analysis is performed on the process to
try many different combinations of resource levels automatically, and finally
analysis of variance (ANOVA) is performed to select infeasible products that
can be excluded from future production plans, this will have a positive effect on
the return on investment for the organisation.
