The scheduling of multiple products through pipelines, to meet a demand over a considered time horizon, is a challenging problem that many researchers have been interested in. Although pipelines are considered mainly in the petroleum industry, they can also be used in other industries. This paper deals with the multiproduct pipeline network schedul...

Open-pit phosphate mine is characterized by a stack of layers with different chemical characteristics (Source qualities SQ). The extraction process involves various elementary operations performed by a dedicated or polyvalent machines. The tactical mining scheduling consists to define the blocs to be extracted and assign the machines over the plann...

Internet of Things (IoT) shows no sign of slowing down, particularly in the field of mobile applications because many IoT devices can be controlled through an application on a smartphone. There is a clear intersection between the Internet of Things (IoT) and artificial intelligence (AI). IoT allows you to connect machines and use the data generated...

This paper describes the basis of a Decision Support System (DSS) designed to schedule fertilizer production orders to be delivered within time windows, in plants made up of multiple heterogeneous parallel processors (production lines), considering that fertilizer production rates and nomenclatures depend on lines, that setup times depend on sequen...

In Web Service research, providing methods and tools to cater for automatic composition of services on the Web is still the object of ongoing research activity. Despite the proposed approaches, this issue remains open. Our current contribution deals with this topic and presents a Dynamic Web Service Composition Framework (DWSC). The DWSC behavior i...

Abstract—as open-pit mines consist in the accumulation of ore layers of different characteristics, their extraction process results from the iteration of a sequence of elementary operations performed on parcels by specialized or multipurpose machines. Medium-term extraction programming consists in deciding the assignment of the available machines o...

In this paper, we propose a hybrid approach for the multi-product straight pipeline scheduling problem. The straight pipeline is shared for the transport of the different quality of phosphate slurries from the pumping station to the distribution center. The objective is to schedule a sequence of batches that ensures all daily product demand with a...

In the old days, networking in Android was a nightmare. Nowadays the problem is to find out which solution fits better the project's necessities. Therefore, almost every Android applications use a Web REST API for data transfer. Previously, developers preferred to write their own code to retrieve and analyze data. However, they now have a whole ran...
