This paper presents a method for the multiple autonomous vehicles mission flight planning in changing weather conditions. We model UAVs fleet servicing spatially-dispersed customers terms of declarative modelling framework. The considered problem boils down to predictive and reactive delivery missions within specified timeframe. Due need implement an emergency return UAV its base, or handle var...

Many real-world manufacturing problems are too complex to be modelled analytically. In these scenarios simulation-based optimisation is a powerful tool to determine optimal system settings. While traditional optimisation methods have been unable to cope with the complexities of many real-world problems approached by simulation, soft computing techniques have proven to be highly useful. This pap...

Definitions Soft sensor is a common name for software where several measurements are processed together. There may be dozens or even hundreds of measurements. The interaction of the signals can be used for calculating new quantities that can not be measured. Soft sensors or inferential calculators are operators' virtual eyes. Soft sensors create windows to a process where physical equivalents a...

This paper presents an exact model for the resource investment problem with generalized precedence relations in which the minimum or maximum time lags between a pair of activities may vary depending on the chosen modes. All resources considered are renewable. The objective is to determine a mode and a start time for each activity so that all constraints are obeyed and the resource investment co...

The location-routing problem is the most significant and yet new research field in location problems that considers simultaneously vehicle routing problem features with original one for achieving high-quality integrated distribution systems in beside of the global optimum. Simultaneous pickup and delivery based on time windows are the two main characteristics of logistic management that have be...

This paper aims to study the locomotive assignment problem which is very important for railway companies, in view of high cost of operating locomotives. This problem is to determine the minimum cost assignment of homogeneous locomotives located in some central depots to a set of pre-scheduled trains in order to provide sufficient power to pull the trains from their origins to their destinations...
