“…In this section, we present a lower bound for our problem by using scenario grouping. The scenario grouping idea is previously considered by Sandıkçı and Özaltın (2017) and Mahmutogulları et al (2018) in mixed-integer multi-stage stochastic problems. The proposed lower bound is used in the algorithm presented in the next section.…”

“…At stage t, the random cost is the total service cost at stage t. The DEP of risk-averse multi-stage SSLP can be modeled by using parameters and decision variables for each node of the scenario tree. Moreover, linearization of mean-CVaR risk measure is possible by defining additional auxiliary variables and constraints (see, for example, Mahmutogulları et al 2018).…”

“…However, the fact that UPM often lead to suboptimal solutions to the second-stage problem problem in which variability is falsely reduced is well-known in the academic literature (Takriti and Ahmed 2004;Barbaro and Bagajewicz 2004). Mahmutogullari et al (2018) presented a scenario tree decomposition approach to handle general risk-averse mixed-integer multi-stage stochastic problems based on the Conditional Value-at-Risk (CVaR) measure. Their approach is tested on a lot-sizing problem under stochastic costs.…”
