“…For example, several works model the sequencing aspect of the problem using a DD (Cire et al 2019, Ploskas et al 2019, Serra et al 2019, Hosseininasab and van Hoeve 2021 since other alternatives would involve big-M constraints that have a loose linear relaxation.…”

In the last decade, decision diagrams (DDs) have been the basis for a large array of novel approaches for modeling and solving optimization problems. Many techniques now use DDs as a key tool to achieve stateof-the-art performance within other optimization paradigms, such as integer programming and constraint programming. This paper provides a survey of the use of DDs in discrete optimization, particularly focusing on recent developments. We classify these works into two groups based on the type of diagram (i.e., exact or approximate) and present a thorough description of their use. We discuss the main advantages of DDs, point out major challenges, and provide directions for future work.

“…Based on this simulation model, Singh et al introduced a new model which accounts for conduction along the fins (tube‐to‐tube) to improve the simulation accuracy. Ploskas et al treat CoilDesigner as a black‐box system and proposed a derivative‐free optimization algorithm to optimize circuitry arrangements. The results show that this method can find optimal or near‐optimal refrigerant circuitry designs after a relatively small number of circuit simulations.…”

Design of finned-tube heat exchangers or coils, and in particular their refrigerant circuits, depends primarily on experimental data and the associated development cost is in general rather high. Taking into consideration the high number of possible refrigerant circuits, the input of each circuit into a particular design computational tool would be a very time-consuming operation. In the present work, we present a model to automatically generate refrigerant circuits for finned-tube heat exchangers based on a recursive algorithm. The model assumes that a tube is only connected to those that are in its neighbourhood. In this way the total number of connecting bend tubes is a minimum and, as a consequence, material usage is at its lowest level. In addition, a finned-tube heat exchanger performance simulation model is developed to evaluate the performance of a finned-tube heat exchanger with the automatically generated circuit. This simulation model can handle arbitrary refrigerant circuits and it is sufficiently user-friendly to allow the easy inclusion of new features. In addition, it can simulate coil performance by analyzing the coil into uneven length elements and by considering non-uniform air distribution at minimal computational cost. The simulation results of the model have a maximum AE10 % error compared with experimental data, most within AE5 % deviation of the experimental data. The automatically generated circuits are evaluated on the basis of the heat exchanger performance simulation results. This combined feature has the potential of being a powerful tool in designing finned-tube heat exchangers.
