“…Sequential pumping of the transported product batches. The tasks of sequential pumping are very complex and diverse [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Studies of these processes began at least half a century ago, monographs were written, and many priority technological problems were solved [5].…”

“…The flow of work does not dry out, they are mainly devoted to problems that have arisen due to changes in the conditions for the operation of pipelines and the emergence of new technologies. Let us give a brief description of some works [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. A description of the technology, current state and problems of sequential pumping of oil and oil products can be found in the monograph [8].…”

“…and much attention is paid to the rationalization of the computational procedure. The publication [11] proposes a decomposition approach that combines heuristic procedures and mixed integer linear programming models. This approach provides for inventory management and process control, taking into account such operational aspects as simultaneous deliveries and predetermined maintenance periods for tanks and pipelines.…”

“…The accuracy of the model is in this case less important than the accuracy of determining the heat transfer coefficient KT(x). 11 As already noted, KT(x) can be considered a piecewise constant function. Then the function T(x) can also be written in analytical form.…”

Regular regimes of oil and oil products pipelines are studied. The problem is to develop an algorithm of effective pipeline system control that ensures the fulfillment of specified boundary conditions at the system boundaries. The product is pumped in batches, the flow is characterized by a change in temperature and pressure flow parameters over time. The developed solution method uses the principle of decomposition in the sense that each computational iteration is im-plemented in 3 stages, in three nested loops. The inner cycle is connected with the material bal-ance relations, at the next cycle the flow equations are introduced and the fulfillment of the 2nd Kirchhoff's law is monitored. If the flow process is significantly affected by temperature, then an external cycle is also implemented, correcting the solution so that the energy conservation equa-tion is satisfied. In the calculation procedure, some computational difficulties may arise, which consist in choosing an appropriate optimization method. On a specific example, the possibility of using various library programs to solve the problem was checked. The developed method is suita-ble for the analysis of systems of arbitrary topology. Since the method is not time-consuming, it can be recommended for online control of oil and oil products supply systems. The paper opens a new direction in the theory of hydraulic circuits. It uses both traditional methods of continuum mechanics and stochastic models.

“…The goal of scheduling transport operations in a pipeline system is to meet the local demand of each linked node, ensuring proper stock control while adhering to many operational limitations such as flow rate constraints. [2]. Pipeline short-term scheduling is a difficult problem, for which a number of mixed-integer (non)linear programming (MI(N)LP) formulations have been developed and described in the scientific literature [3].…”

In this paper, we describe the efficient discrete modelling of multiproduct pipeline systems in Witness simulation software environment. Our simulation model consists of 6 blocks called System structure, Pumping modes, Pumping schedule, Pumping execution, Collecting of outputs and Simulation run control and is supported by MS Excel. Algorithm for the assignment of a scheduled pumping requirement to execution is proposed too. Our model is innovative in that pipelines for the transport of products, tanks for storing products in warehouses as well as the products themselves and their material flow are represented neither by the continuous physical elements (Pipes, Tanks, Fluids) nor their discrete equivalent (Conveyors, Buffers, Parts) but by the logical elements called Variables. Avoiding physical elements enables efficient modelling of bidirectional flow of products in a pipeline and furthermore leads to the high speed of a simulation run. Based on the outputs of simulation of a simple pipeline system we show how our model can be used to support scheduling in complex multiple sources, multiple destinations pipeline networks.
