Road Traffic Simulation for City Planning: New AnyLogic Library in Action! 07.04.2016 Stepan Egorov

When planning new transfer hubs, developers need to verify the stations would provide expected passenger capacity, while city authorities have to learn how building a station would affect traffic in the area and public transfer load. Simulation modeling is a perfect instrument for solving such challenges. We covered, in a past blog, one of the models built for the Moscow Ring Railway project, passenger flow simulation at Cherkizovo transfer hub, where a station layout was tested at peak passenger loads. The project we are going to discuss today is another model of Moscow public transport system. We will talk about automobile traffic flow research at the transport hub of Volokolamskaya, done by ITS Consulting. [...]

Warehouse Modeling and Optimization Saves Millions for Cardinal Health 09.02.2016 Stepan Egorov

Being #26 in last years’ Fortune 500 list, Cardinal Health is a billion dollar pharmaceutical distribution and logistics company. Its clients are hospitals, pharmacies, physicians, and individual consumers. They face a multitude of typical distribution warehouse challenges that are further complicated by the nature of pharmaceutical products, which are smaller in size, consumable, expensive, and could be life critical. Company’s warehouses have narrow passages, and workers operate big multilevel trolleys. That increases the probability of employees’ mistakes and makes these mistakes costly. [...]

Automated Production Line Optimization: Case Study 26.01.2016 Stepan Egorov

Centrotherm Photovoltaics AG is a global supplier of technology and equipment for the photovoltaics, semiconductor, and microelectronics industries. The company needed to identify the best configuration of the automated production line and factory, to minimize costs and maximize throughput and reliability. Throughput and equipment utilization rate metrics were utilized to compare alternatives. Centrotherm needed to avoid possible bottlenecks in the material flow and optimize in-factory logistics. Also, management required taking into account casualties and stochasticity, for instance, the probability of scrap or how the factory would operate in case of equipment breakdowns. [...]

Modeling Healthcare at Different Abstraction Levels 02.06.2015 Stepan Egorov

There are many cases of simulation modeling in healthcare. Application areas can vary, from process optimization in hospitals to macrolevel agent-based epidemiology models. Due to its multimethod nature, AnyLogic allows models to be built at various abstraction levels. A good illustration of how researchers and consultants can apply the same tool to different problems is the three models built by the Stockholm County Health Administration in Sweden. The models included macro, meso, and micro abstraction level applications in healthcare simulation. The microlevel model simulated the maternity ward in a hospital that was currently under construction. The purpose of the model was to support discussions related to which resources, capacity, and work methods were required in the new ward. One relevant discussion was whether to keep mother and child in the same room during their entire stay or to have dedicated rooms for antenatal care, delivery, and postnatal care. [...]

Production Plan Optimization at Ice Cream Manufacturing Plant 12.05.2015 Stepan Egorov

Conaprole, the biggest dairy production company in Uruguay, produces more than 150 SKUs in their ice cream plant, using five production lines, and up to five different packaging configurations for each line. The company plans ice cream production on a 12-month rolling basis as part of the Sales & Operations Planning process, and the demand plan varies a lot due to seasonality. The factory management needs to prepare the production lines for the peak season during the low season, taking into account product shelf life and the warehouse’s freezing cameras’ capacity and costs. The factory was often unable to meet the high season demand that generated stock-outs. In addition, management found it very difficult to reschedule quickly their detailed plans due to the challenges they faced including bottlenecks, production process constraints, and staff turnover.

Managing River Logistics with Simulation 21.04.2015 Stepan Egorov

Inland waterway logistics have their own special aspects that include high seasonality due to weather conditions, long delivery times, restricted door-to-door delivery capabilities, and more. On the other hand, river transport is cheap, environmentally friendly, and allows large amounts of goods to be carried. Barges are widely used to carry both bulk cargo and containers. Simulation can help companies justify switching to river logistics by comparing water transportation to other means in terms of costs, throughput, or shipping time. Shipping operators can use simulation to optimize routing and fleet management policies, taking into account uncertainties, breakdowns, bottlenecks, weather conditions, and water level. The following is a success story of river transport simulation-based optimization in South America. [...]

City Rail Transfer Hub Simulation 24.09.2013 Stepan Egorov

How can an overpopulated city fight traffic congestion? Examples from many current metropolitan areas show that, apart from subways and buses, city railways can greatly improve traffic situations. Probably the most famous city rail system is the S-Bahn in Germany. In North America, one of the more well-known examples is the BeltLine in Atlanta, Georgia.

Can one make precise forecasts of consumer behavior? 05.09.2013 Sergey Suslov

Many people, who are interested in sales forecasting, are familiar with the book Predictably Irrational by Dan Ariely. The abstract of the book states: “Dan Ariely refutes the common assumption that we behave in fundamentally rational ways. From drinking coffee to losing weight, from buying a car to choosing a romantic partner, we consistently overpay, underestimate, and procrastinate. Yet these misguided behaviors are neither random nor senseless. They're systematic and predictable—making us predictably irrational.” The irrationality of human decisions is the basis of behavioral economics. Predictably Irrational, and many other books, give many examples which argue the idea of consumer rationality. Businesses are irrational too, as they are guided by human beings.
