PDA Sie sind hier: Home Lexikon Erlang (Programmiersprache) Erlang (benannt nach Agner Krarup Erlang ) ist eine Programmiersprache , die bei Ericsson von Joe Armstrong und anderen entwickelt wurde. Spricht man von Erlang, meint man meist nicht nur die relativ kompakte Sprache, sondern auch das Laufzeitsystem und die umfangreiche Bibliothek. Zusammen wird das System Erlang/OTP genannt, wobei OTP eine Abkürzung für The Open Telecom Platform ist. Es handelt sich dabei um eine Middleware für den Bau verteilter, hochverfügbarer Systeme. Positiv hervorzuheben ist z.B. die verteilte Datenbank Mnesia. Erlang wurde ursprünglich für die Programmierung von Anwendungen in der Telekommunikation geschaffen, insbesonders für Vermittlungsstellen von Telefonnetzen ( Switch Die dort vorhandenen besonderen Anforderungen, gingen unmittelbar in den Entwurf der Programmiersprache und des Laufzeitsystems ein: Parallelität hohe Verfügbarkeit Fehlertoleranz Auswechseln von Modulen zur Laufzeit etc. Erlang genügt den Paradigmen der funktionalen nebenläufigen und verteilten Programmierung.

Themen Ratgeber Shopping Forum ... PDA Sie sind hier: Home Lexikon Erlang C Erlang C ist eine spezielle Form der Erlang-Verteilung , die der dänische Mathematiker Agner Krarup Erlang am Anfang des 20. Jhd. entwickelte, um die Wahrscheinlichkeit von Wartezeiten bei der Telefonvermittlung zu benennen. Damals wurden Gespräche per Hand "vom Fräulein im Amt" gestöpselt - wie lange würde also die Wartezeit betragen, wenn die Gespräche inkl. ihrer Nachbearbeitungszeit eine gewisse Zeit dauern würden und man dies für ein Intervall von 15 oder 30 oder 60 Minuten berechnen wollte. Kurz: Die Menge der Gespräche multipliziert mit ihrer Gesamtdauer wird durch die Sekunden des Intervalls geteilt. Heute wird Erlang C vor allem in Callcentern eingesetzt, um die Personaleinsatzplanung zu unterstützen. Kritik an Erlang C wird vor allem laut, weil die Formel nicht die Anzahl der Leitungen berücksichtigt und auch nicht die Anzahl derer, die sofort wieder auflegten - auch die Toleranz der Wartenden ist für die Formel uninteressant. Die ursprüngliche Formel, die der Mathematiker Erlang für dieses Problem aufgestellt hat, sieht wie folgt aus:

CWI Syllabi CWI Syllabus 43 Rekenen op het toeval VC '97 (in Dutch) This book contains the courseware of the 51st annual course for mathematics teachers, this time dealing with statistics and probability The first lecture by I.H. Stamhuis outlines the development of statistics from a purely verbal, qualitative discipline to modern statistics (descriptive statistics and mathematical statistics). Ms. Stamhuis lets her story start in the early nineteenth century with the person of Adriaan Kluit (the first Dutch professor in statistics) and continues until the early twentieth century with Galton and Pearson. W. Kleijne describes the earliest beginnings of probability theory, i.e. the work of Christiaan Huygens ( De Ratiociniis in Ludo Aleae , 1657), translated in 1660 by him into Dutch as Van Rekeningh in Spelen van Geluck . It analyses the discussions on dice and hazard games. Also at the same time, the rise of the actuarial mathematics is described. A.G.M. Steerneman in a way continues Stamhuis ' lecture. His aim is a more precise definition of the concept of estimation. According to his lecture, the essence of statistics is drawing conclusions from incomplete and inaccurate observations and approximating the level of confidence of the result. J.H.A. de Smit

Home Contact Us Search: Call Center Consolidation - Does It Still Make Sense? By Ike Mitchell Principal, Computer Sciences Corporation One of the surest ways for a call center operator to achieve improvements in both service quality and cost performance is to take advantage of economies of scale. To gain these efficiencies, fewer, larger agent groups are often better than having many small agent groups; operating larger centers is often better than operating many small centers. In the past, there have been practical limits to how large an agent group or center could grow. Issues like training, database access and the size of the labor pool constrained the efficiencies that could be gained through scale. Physical limitations remain but, increasingly, new technologies and old business practices can enable enterprises to consolidate groups into larger "virtual" centers. Indeed, such "virtual" consolidation has been the trend in recent years. The tragedy of September 11 demonstrates the need for disaster recovery and redundancy, and for greater physical distribution of facilities. But the idea of consolidating centers and operations doesn't always run counter to this trend. In fact, some of the technologies and business processes discussed below enable call centers to become truly "virtual" rather than just physically distributed. Moreover, the renewed emphasis on disaster recovery is only one of many factors to be considered in an overall economic analysis. The slowing economy demands that customer contact be managed from a cost/performance point of view, and increased competition demands improved service performance. Consolidation, logically and physically, can achieve these seemingly incompatible goals.

Eponyms An eponym is a word derived from the name of a real, fictional, mythical or spurious character or person. Most eponyms originate from a person's surname: boycott , for instance, from the Irish landlord Captain Charles Cunningham Boycott; dahlia , from the Swedish botanist Anders Dahl; the sousaphone , from the American bandmaster John Philip Sousa; and volt , from the Italian physicist Count Alessandro Volta. Many eponymous words come from literary, biblical or mythological sources: malapropism , from Mrs Malaprop in Sheridan's The Rivals Dickensian , from the English writer Charles Dickens; as old as Methuselah , from the age of the Old Testament patriarch; and aphrodisiac , from the Greek goddess of love and beauty Aphrodite. There are thousands of eponyms in everyday use in English today and study of them yields a fascinating insight into the rich heritage of the world's most popular language and its development. Here are some more examples of names that have been immortalised in such a way. A B C D ... W X Y Z A Aaron's beard/rod Aaron, brother of Moses

økonomiske utvikling ved hjelp av teoretiske modeller som utnytter innsamlete, relevante data. I prinsippet er ikke det noe annet enn det arkitektfirmaet "Snøhetta" gjør når de bygger en mindre modell av det nye operabygget for at de selv og andre interesserte skal få et godt og forhåpentligvis realistisk bilde av hvordan bygget vil ta seg ut i virkeligheten. Modeller er altså verktøy til å beskrive og styre virkelighetens verden. Det er verdt å merke seg at vi ønsker å utlede matematiske resultater på en slik form at de er velegnet for numeriske beregninger. Når den matematiske modellering "møter veggen", må simuleringer på datamaskin overta. For så til slutt å sjekke om modellen og de avledede resultater er i overensstemmelse med data fra virkeligheten, benytter en seg av teknikker fra den statistiske metodelære. Kunder ringer inn på tilsynelatende helt tilfeldige tidspunkter. Siden sentralen har begrenset kapasitet, risikerer kunden å få et opptattsignal. Unngår kunden dette, vil vedkommende i beste fall umiddelbart få en ledig linje. Hvis ikke, blir kunden plassert i kø, utsettes for ikke altfor smektende musikk og med jevne intervaller gitt beskjed om at "du rykker stadig frem i køen". Kunden kan da etter en stund gi opp og legge på røret eller vente til det blir en ledig linje.

Recent studies show that calls average 45 seconds in queue prior to being answered by a call center service representative.* The Unity Call Center Group uses every means to assure that there will be the right number of people available to answer calls for every project. One such tool is the use of Erlang Tables for scientific scheduling. Agner Erlang developed his scientific mathematical tables for the use of the Copenhagen Telephone Company in 1917, and the theories still hold true today. Erlang is to Call Center Scheduling as Einstein is to the Theory of Relativity. In 1917 he developed his Erlang Tables - an accurate and concise set of calculations that show exactly the number of agents needed to answer phones within a given number of seconds. The use of modified Erlang tables enables Unity to price accurately and allows customers to have some control over cost by adjusting the parameters of the project. With three variables identified, Unity knows how many agents each customer will require.
