Resource allocation, product batching and production scheduling are three different problems in manufacturing systems of different structures such as flexible flow shop manufacturing systems. These problems are usually dealt with independently for a certain objective function related to production efficiency and effectiveness. Handling all of them...

This study integrates the learning rate factor into the design of a new production line, thereby increasing the complexity and enhancing the realism of the line balancing problem. Given the NP-hard nature of line balancing problems, a heuristic method termed rank positional weight with learning rate (RPW-LeRa) was developed to address this challeng...

The resilience of critical infrastructure systems to disruptions is a paramount concern in contemporary society. To address this, the current study evaluates the effectiveness of several machine learning models for optimizing the restoration of interdependent infrastructure networks following disruptions to enhance their resilience. The models asse...

In many countries, the accessibility of blood and blood products remains a challenge due to the complex supply chain, short product lifetime, fluctuating demand at the hospital level, and timely access. To address this challenge, some countries have implemented the use of drones to deliver blood products to remote healthcare facilities, resulting i...

In view of the perishable nature and complex storage requirements of certain blood products, the delivery of blood groups from blood banks to hospitals is a key aspect of the healthcare system. The centralization of blood supply facilities for economic reasons and an increase in traffic volume have led to significant delays in the use of traditiona...

Numerous technoeconomic factors have had a considerable impact on the industrial and service sectors. The best uses of production and service resources have been a main research area. Capacity planning, which aims at the optimum utilization of resources, has attracted a lot of scholarly attention. To the best of our knowledge, however, there has ne...

Community structures exist in different infrastructure networks such as water, gas, and power networks among others, where each network is split into multiple sets of components. Such sets are sparsely connected but have densely connected components within each one of them. However, critical networks often depend on each other to function properly....

Infrastructure networks such as power, communication, gas, water, and transportation rely on one another for their proper functioning. Such infrastructure networks are subject to diverse disruptive events, including random failures, malevolent attacks, and natural disasters, which could significantly affect their performance and adversely impact ec...

Critical infrastructure networks, including water, power, communication, and transportation, among others, are necessary to society’s functionality. In recent years, the threat of different types of disruptions to such infrastructure networks has become an increasingly important problem to address. Due to existing interdependencies, damage to a sma...

Critical infrastructure networks are often described as (i) interdependent in nature for functionality, (ii) vulnerable against multiple natural or artificially caused hazards, and (iii) vital for providing the essential needs and ensuring the operability of societies. Developing a comprehensive plan for infrastructure network resilience is enabled...

Community structures exist in many infrastructure networks (e.g., electric power, water distribution, natural gas) where each network is partitioned into sets of densely connected components with sparse connections between them. Such community structures are formed in infrastructure networks based on physical connections within each network or thei...

Critical interdependent infrastructure networks such as water distribution, natural gas pipeline, electricity power, communication and transportation systems provide the essential necessities for societies and their utilization is the backbone of everyday processes such as production, health, convenience and many more. Often cascading dysfunctional...

Critical infrastructure networks such as transportation, telecommunications, electric power, natural gas and oil, and water distribution rely on one another for their proper functionality. Hence, they are increasingly interdependent, making them highly vulnerable, where the occurrence of even a small disruption in one infrastructure network could p...

Modern communities heavily depend on critical infrastructure networks, such as power, water, gas, telecommunications, and transportation. These infrastructure networks are often dependent upon each other for operation. The interdependence of infrastructure networks makes them more vulnerable to disruptive events, such as malevolent attacks, natural...

Where previous work in planning for disruptions to critical infrastructure networks emphasized prevention and protection, such planning has recently shifted more broadly to capture the ability of infrastructure networks to withstand a disruption and recovery timely from it. The ability to withstand, adapt to, and recover from a disruption is genera...

Critical infrastructure networks such as electric power, water distribution, natural gas, transportation and telecommunications are the backbone of modern societies as they provide them with the services that are essential for their continuous functioning. However, these infrastructure networks are not isolated from each other but instead, most of...

Many critical infrastructure networks that dot the global landscape often rely on each other in different ways for each to be functional. Government planning documents around the world recognize the interdependence of these infrastructure networks. But naturally infrastructure networks do not exist for their own operation but because society relies...

The purpose of the components of this research is to develop a restoration modeling approach and importance measures that (i) enhance the resilience of the set of interdependent infrastructure networks, and (ii) capture the physical interdependency among the infrastructure networks. The first research component is optimizing the restoration of inte...

Critical infrastructure networks are the backbone of modern societies as they provide them with the services that are essential for their continuous functioning. However, these networks are increasingly becoming more interdependent, potentially making them highly vulnerable. Hence, analyzing the vulnerability of these interdependent infrastructure...

Analyzing network vulnerability is a key element of network planning in order to be prepared for any disruptive event that might impact the performance of the network. Hence, many importance measures have been proposed to identify the important components in a network with respect to vulnerability and rank them accordingly based on individual impor...

As demands are growing and networks are becoming more complex every day, the cost and consequences of even a small disruption in the network is going to be huge. Analyzing and prioritizing edges for the recovery of the complete network is essential for a successful continuity of business operation. Measuring the importance of network components is...

In this paper, we study the problem of base stations location and configuration. Antenna configuration includes number of antennas installed at the base station, the azimuth of each base station, the tilt, height, and transmitted power for each antenna for cellular mobile networks. Towards this end, a mathematical model is formulated using integer...

The planning of cellular mobile networks faces several major challenges such as the rapidly growing demands for mobile communication services, the limited bandwidth available for radio networks, and the requirements of the new emerging technologies. Therefore, an efficient planning model is required to design and implement a cellular network regard...
