7. MCQueue: educational software for Markov Chains and Queues (non-commercial use)

This software package contains two modules. The first module is for the transient and steady-analysis of discrete-time and continuous-time Markov chains up to 100 states. The other module calculates performance measures including queue-length probabilities and waiting-time probabilities for basic queueing models (M/G/1 queue, M/M/c queue, M/D/c queue, G/M/c queue, M/M/c/c+N queue, the transient M/M/1 queue). The algorithms in this software package are based on methods discussed in the book H.C. Tijms, A First Course in Stochastic Models, Wiley, 2003. Download here the zip-file.

8. Orstat2000: educational software for applied probability and operations research

This software package is a polished and extended English version of software that was originally developed to promote probability and operations research in the senior forms of Dutch high schools (and early college). The software package contains modules for coin-tossing, roulette, Buffon's needle problem, central limit theorem, simulation of queues, traveling salesman problem, dynamic programming, linear programming, and integer programming amongst others. For non-commercial use, the full version of the software package ORSTAT2000 can be downloaded free of charge: Download here the zip-file.

9. New book Probability, A Lively Introduction, Cambridge University Press, 2017

There is no book I have written with more enthusiasm and dedication than this introductory textbook on probability. The students are the focal point, and much effort has been taken to make the book truly readable for them. Inessential technicalities are avoided wherever possible. There are some 750 problems and 150 examples, all carefully selected for being both appealing and illuminating. Perhaps the most important difference from other introductory probability books is the section of detailed solutions to all odd numbered problems, with the goal of actively engaging the student in the learning process.

A solutions manual with solutions to all problems is available to qualified university instructors who have adopted the book as a required text for their course. When sending a request for the solutions manual, please provide a syllabus and/or webpage for the course.

11. Wiskunde-D module Optimalisering in Netwerken

Deze wiskunde-D module is een avontuurlijke reis langs niet-aangeharkte paden door het gebied van de optimalisering in netwerken en richt zich op leerlingen in 5 en 6 VWO. De module bevat uitdagende stof voor zowel leerling als leraar en laat zien welke boeiende toepassingen de wiskunde in de praktijk heeft. Vele praktische problemen in uiteenlopende gebieden kunnen worden geformuleerd als een optimaliseringsprobleem op een netwerk: kortste-pad probleem, handelsreizigersprobleem, routeringsproblemen, etc.

12. Nieuw: Kansrekening van Alledag, een Wereld vol Verrassingen

Dit boekje over kansrekening in het leven van alledag is ontstaan uit een serie populair-wetenschappelijke columns die ik geschreven heb voor het huisorgaan van de Nederlandse Vereniging voor Statistiek en Operationele Research. Het boekje bestaat uit 16 korte hoofdstukken die onafhankelijk van elkaar gelezen kunnen worden. De onderwerpen die in de diverse hoofdstukken aan de orde komen zijn boeiende en leerzame toepassingen van de kansrekening uit het leven van alledag. Het materiaal kan als lesstof gebruikt worden, maar leent zich ook voor werkstukken waarin de stof verder wordt uitgediept. De inhoudsopgave alsmede de tekst van het eerste hoofdstuk zijn bevat in de file KansrekeningAlledag. Het boekje is verschenen bij de wiskunde uitgeverij Epsilon in Amsterdam en de prijs van het boekje is 12 euro.
