Warehouses and conveying systems

Warehouses and storehousess, and the automated or manual conveying systems that generally astructure them are issues of important consequences: it is necessary to avoid shortages of conveying elements, blockages in intermediate areas, to find acceptable response times, gain square meters, absorb fluctuations in orders, and size docks, fleets, etc. sometimes according to fine adjustments on conveyor speeds.

The accumulation conveyors offered in ExtendSim allow a very subtle configuration of their role in a conveyor system. Some aspects were detailed in a dedicated article.

This project intended to size the pallet transport equipment, in order to assess the number of AGVs needed in the warehouse, estimate the average response time to an order, as well as the maximum possible load for the warehouse.

For each movement of an AGV, an algorithm in the model searches for the shortest route between its starting position and its destination, and also manages the vehicle’s route for possible crossings with another vehicle.

Etude dynamique de réseaux de transport en commun

Initialement développé pour des entreprises gestionnaires de réseaux de transports publics, UrbaSim est devenu une application à part entière, utilisable par les opérateurs de transports publics comme par les consultants qui effectuent pour eux des études.

UrbaSim permet de décrire un réseau de métros, bus, tramways, ou d’une combinaison de véhicules, et de mettre à l’épreuve son fonctionnement, soit pour découvrir les points à améliorer dans l’usage quotidien, soit pour voir la réactivité à des événements spéciaux (match de foot, braderie, vacances), soit pour tester en conditions réelles des changements futurs (nouvel arrêt, horaires modifiés, capacité différente d’un nouveau matériel roulant, variation de la demande voyageur, etc.).

  • Indicateurs de qualité du service : nombre de laissés à quai, attente, niveau de confort dans les véhicules.
  • Indicateurs d’utilisation des ressources : nombre de voyages ou de kilomètres, taux de remplissages des véhicules, affluence sur les quais.
  • Graphiques de suivi pour un véhicule ligne particulier, ou pour un arrêt précis.
  • Graphique d’évolution de la charge, graphique Serpent de charge.

L’interface utilisateur s’appuie à la fois sur MS Excel et sur MS Access, pour faciliter la saisie des données et leur récupération. Chaque simulation peut être jouée sur une carte Google Earth, permettant d’associer le réalisme du rendu et la prise en compte intuitive des phénomènes de congestion ou de blocage.

Airports and terminals issues

HUBSIM is a comprehensive solution to simulate and optimize passengers flow in airports. This application simulates precisely every single passenger from arrival plane landing to departure plane boarding in large multi-modal infrastructures. It takes into account walking traveling time, passport and/or baggage checking (with resource affectation optimization), finite capacity bus or shuttle transfers in large airports, as well as different passenger types (high/low contribution, reduced mobility PAX, children etc.).

Shuttles routes and timetables, check-point size, door assignment to planes, are all factors contributing that a passenger catches a connecting flight. ExtendSim simulates a whole day at Charles de Gaulle Airport in less than 5 minutes (about 100 000 PAX). User-friendly interface and easy import/export to MS Access database allow users to setup scenarios and make customized reports. HUBSIM becomes the perfect tool for precise infrastructure design, security and evacuation planning and management.

Managing flows of people

In public buildings, administration offices, and transportation facilities, security issues are added to various constraints:

  • Different populations: visitors, employees, etc.
  • Horizontal circulation from one room to another, and vertical (lifts and staircases).
  • Optimal sizing of reception desks and incoming calls management.
  • Security control checking shifts.
  • Extreme conditions at peak hours.
  • Side flows of deliveries, technical staff, couriers.
  • Limited capacity of common spaces (cafeteria, waiting room).

Simulation provides many tools to validate a fluid circulation of user groups, to make sure parking access does not jam the main street, to test the response algorithm of lifts or the proper sizing of access control points, and anticipate flows in case of evacuation.

Two approaches simulating flows of people/passengers/pedestrians/visitors

1 – The study aims the functional aspect of the system, that also includes other types of flows (cars, workstations, tools or various resources) : it’s a quite typical case of discrete simulation, ExtendSim should be favored to take into account many others aspects or constraints than persons going from one point to another.

2 – The study focuses on pedestrians, that are precisely located within a known geometry (various buildings) that plays a large part in the constraints set on flows : it’s a case of multi-agent simulation to be rather treated with Pathfinder, because of the specific movement of persons, of the part played by their environment, of the 3D rendering of results.

Healthcase systems issues

Healthcare sector has been using simulation for long, as part of the teaching and research process. Simulation should also take place to better understand the flows circulating in the complex systems that are care units, hospitals centres or medical laboratories.

Simulation helps managing different skills and schedules, reducing cycle time, delays and stocks, dimensioning equipments.

A simulation model for this medical Laboratory enabled to:

  • Dimension the various analysis devices.
  • Dimension the number and size of incubators.
  • Optimize dispatching on multi-purpose equipments.
  • Define analysis protocols.
  • Define shifts and tasks for operators.
  • Ensure permanent capacity at the lowest investment and working costs.

Uniquely adapted for Process Flow Analysis

For all process industries process – chemical, pharmaceutical, oil, polymer, paint industries – whether with continuous or batch operations, a simulation study sharpens the managing rules, flow control and organization decisions so as to:

  • Choose money-saving production series complying with fluctuating product mix.
  • Test and compare different equipment configurations
  • Reduce generation of unwanted products
  • Size silos, hoppers, tanks, production batches
  • Resist random variation of raw materials and orders
  • Visualize functionality in terms of throughput and predicting the limits of each solution

ExtendSim is specially adapted for this kind of issues, with its Rate library meant for flows like powders or liquids (or bulk material), moving through the model controlled by valves, merged or separated according to realistic rules, reproducing precisely the operations met in process industry.

This model simulate a chemical plant constrained by a limited water resource : it revealed mandatory to adjust the operation sequence to favor the more water-efficient, to validate the equipment size (tanks, centrifuges, heat exchangers), and in the end favor specific production schedules where water was better used.

Consumer Packaged Goods Industry

In food industry, constraints are numerous and specific: variable demand and seasonality, wide customization of products, mix of continuous and discrete flows, and very specific production equipment. Add to this very strict cleaning regulations and speed constraint to maintain fresh products during the whole process. Models in food processing are confronted to two kinds of issues:

In manufacturing the product, the model will include:

  • A global or calendar production schedule (seasonal products)
  • Applying a manufacturing recipe for the product (steps in processing, raw material, proportions in mixing, cooking, etc.)
  • Managing stocks of raw material (replenishment)
    Managing intermediate stocks
    Organizing the cleaning of the whole process (stocks, machines, etc.)
  • Tracing the age of products during process, and managing waste.

The packaging step will include:

  • Manufacturing program for each product (steps, portions, material, labels, etc.)
  • Transportation between each step (conveyors, forklifts)
  • Machines controlling (maintenance, failures) and labor managing (shifts, competencies)
  • Managing stocks
  • Tracing the age of products during process, and managing waste.

Simulation helps reliable decision-making, answering many questions: which batch size, which shift, where reduce cycle and storage?

Logistics & Supply Chains Issues

In the complex choreography of conveyors and forklifts in a warehouse, or interaction between a sub-contractor and a carrier, simulation only can take into account the dynamic side of issues: blockages that occur in certain conditions only, a buffer of wrong size when working with a specific packing unit, all things for what a dynamic replica reveals more reliable than static calculations.

Simulation for logistics must take into account multiple references and routes, bi-modal transportation, conflicting resources, customs routines and delays, out-dating stocks… Animation focuses on bottlenecks and stock alerts.

The model studies a sea port where thousands of tons of various raw material for industry go through. The port can get blocked in reaction to unavailable spots on piers, storage limitations, etc. The aim is to test these constraints and vary the number of resources (ASR vehicles, dockers) and their shifts to manage saturation situations, while taking into account the timetables of tides.

Simulation was very early used in manufacturing industries and capital goods production, as models could represent in details the material flows in a plant or factory, along with machines, operators, breakdowns and changeovers. Simulation helped testing different managing strategies, various scheduling options, taking into account all the physical constraints of the workshop.

The model for this finishing line focuses on a new machine that should replace a manual operation: it has to be studied in its operational context to allow choosing a technology among several, evaluating the machine’s performances, adapting the size of buffers upstream and downstream, reviewing maintenance schedules and even organizing differently production plans.

Services

Service industries and the whole tertiary sector seek to meet a highly variable rate of demand with a hopefully constant rate of service, having to deal with task priority, resource cost, crewing patterns… and random human behavior!

For customer assistance, mail orders, internet sales, in banks, insurance companies, medical assistance and public services, call centers, whatever are their sizes and structure, must be able to quickly direct calls, avoiding a too long waiting time and differed answers.

The sequence of operations and the algorithms for routing calls are usually easily represented in discrete models, and using a simulation software like ExtendSim gives access to statistical distribution laws reproducing the type of calls proportions.

In this call center, the impact of feedback after commercial prospection actions is studied, in order to ensure new incoming demands will be correctly treated, and also to evaluate which sales operations had the best feedback.

The model helped optimize the strategies for routing incoming calls, and to better use the shifts of agents and hotliners.
