=== The bullwhip effect === The bullwhip effect happens along the supply chain as the result of information asymmetry between the organisations involved. The classic scenario is a sudden increase in customer demand as shown in the figure to the right. The sudden demand hike depletes the retailer's stock resulting in lost sales. To avoid this happen in the future, the retailer does not only increase its next order to the wholesaler by the additional customer demand observed in this period, but by a little bit more just to be safe. That is because the retailer knows it takes time for the wholesaler to deliver the larger order. This fear of losing out in future sales is the behavioral component of the inventory problem causing the bullwhip effect. Faced with an unexpectedly larger order by the retailer, the wholesaler will forward an even larger order to the manufacturer. The manufacturer in turn makes a non-reversible decision to increase its production level even more in the nearer future. However, because of the delay in information flow from customers to manufactures, the latter is not aware for several order periods that its production level actually exceeds customer demand considerably. The result of the bullwhip effect in this classic application is an excessive amount of stock held by retailers, wholesalers and manufacturer. The more tiers a supply chain has, the larger the magnitude of the bullwhip effect becomes.
=== System dynamics models in operations contexts === System dynamics models in operations contexts focuses on the importance of how components in a system interact with each other as well as providing an overview of the processes that takes place within the system. Behavioral operations research often benefits from the development of comprehensive systems models as they are able to analyse and provide an insight of the operational system. This allows the study of behavioral operations to understand how people in these settings or work conditions think about the context in which they operate. In an operations system, it often involves levers for managers to manipulate the components involved in the system. The uses of these levers are determined by human behaviors and these behaviors include feelings of stress and fear.

=== Newsvendor problem === The newsvendor model (or newsboy or single-period or perishable) is a mathematical model used in operations management and applied economics to determine optimal level products or services to keep in stock when the demand is unknown. This model is also known as the newsvendor problem by analogy with the situation faced by a newspaper vendor who must make on time stocking decision of how many copies of newspaper to keep in stock when facing uncertain demand. If the newspaper vendor stocks too much, these newspaper may end up worthless by the end of the day as they are no longer up-to-date. However, if the newspaper vendor stocks too little, he misses the opportunity to make more profit and suffers loss of goodwill.
=== Assignment problem === The assignment problem is a complex optimization problem. The problem involves number of agents and a number of tasks. The purpose is to assign each agent with a task. All agents are expected or aimed to be allocated in a way that will maximize productivity and efficiency and minimize the total cost of the assignment.
=== Secretary problem === The secretary problem can also be called the optimal stopping theory. It focuses heavily on applied probability, statistics and decision theory. The idea behind the secretary problem is that to make the best decisions when there is a pool of different options, other options are unknown, details of other options will only be given if the currently existing option is given up. The problem comes down to the idea of optimal strategy, maximizing the probability of selecting the best option.
