The fifth generation achieved tremendous success, which brings high hopes for the next
generation, as evidenced by the sixth generation (6G) key performance indicators, which …

The active strategy series-parallel redundancy allocation problem (RAP) with mixed
components involves setting reliable objectives for components or subsystems to meet the …

Network systems are commonly used in various fields, such as power grids, Internet of
Things, and gas networks. The reliability redundancy allocation problem is a well-known …

Purchasing and procurement managers should make informed decisions in selecting
materials at the right time, in sufficient quantities, and at affordable prices. Supplier selection …

Designing a reliable system under different working conditions is a challenging task for
system designers. This paper introduces different approaches to cope with the uncertainty of …

The joint optimisation of production scheduling and maintenance planning can significantly
decrease production interruptions (or stoppages) and, simultaneously, improve production …

The reliability redundancy allocation problem (RRAP) has been mostly solved either as a
single or as a multi-objective optimization problem. However, this problem also has …

This paper considered a new single-objective redundancy allocation problem with a mix of
components (RAPMC) for a series-parallel system. The components are Binary-State …

Due to its capacity to increase system reliability, cold standby redundancy design has
attracted considerable attention and has been applied in crucial-safety engineering systems …

This paper presents a new single-objective redundancy allocation problem (RAP) for a
system with subsystems in a series–parallel configuration. Different types of binary-state …
