Este es el caso del taller Euroshop de la marca Volkswagen, y tiene tal demanda que en muchas oportunidades se originan largas colas de clientes y la atención que se le da al cliente no es la mejor, muchos de ellos se aburren y regresan otro día; o no se cuenta con los materiales en ese instante. El taller requiere de un sistema que permita a sus clientes reservar una cita previa a la atención, para que no tenga que esperar y se puedan optimizar los recursos del taller en cuanto a organización y planificación para la atención de sus clientes. El objetivo principal de la tesis pretende satisfacer esta necesidad diseñando un sistema electrónico que permita a los clientes reservar sus citas para atención en el taller. En el primer y segundo capítulos se definen el marco problemático y el marco teórico. En el tercer capítulo se realizan las consideraciones para el diseño, que implica un análisis FODA, que nos permitirá destacar los puntos fuertes y débiles de este sistema; y un estudio de mercado que nos dará a conocer el perfil de cliente. Ingresamos al cuarto capítulo para meternos de lleno al diseño del sistema y a la implementación del prototipo. Pudiendo ver fotos y videos del resultado final en los anexos del CD que viene incluido en la contratapa del presente documento. Finalmente, se podrá observar que la presente tesis sirve de punto de partida para otros futuros temas de tesis, con los que se puede enriquecer aún más esta investigación y aplicarla a muchos otros entornos prácticos. (DOCUMENTO DE FACULTAD) TEMA DE TESIS PARA OPTAR EL TÍTULO DE INGENIERO ELECTRÓNICO Título : Diseño de un Sistema Electrónico de Reserva de Citas Para Atención a Clientes en Talleres de Autos Utilizando Tecnologías Web e IVR Área : Comunicaciones Asesor : Ing. Carlos Alcócer Alumno : Roberto Manrique Olaechea Código : 1995.1162.8.12 Fecha : 5 de Setiembre del 2005 Descripción y Objetivos Una de las áreas que la tecnología ha desarrollado y a una velocidad increíble es Internet, tanto es así que se puede comprar diferentes cosas con un solo clic, realizar transacciones bancarias, encontrar información de todo tipo, comunicaciones en tiempo real con cualquier persona en cualquier parte del mundo, y también, realizar reservas para atención al cliente. Actualmente los sistemas para reservas electrónicas de citas para atención al cliente que se encuentran implementados son los sistemas de reserva de citas en el sector salud, en el sector aerocomercial (reserva y ventas de pasajes, reservas para transporte de bienes comerciales) y en la reserva de habitaciones para cadenas de hoteles y también renta de autos. Estos sistemas electrónicos de reserva de citas realizan sus operaciones a través de sus páginas Web o de Centrales Telefónicas (Call Centers). Pero estas Centrales Telefónicas aún están manejadas por personal de la compañía y tienen ciertos inconvenientes. El sistema de citas trae beneficios tanto para el cliente como para la empresa. Haciendo una cita, el cliente tiene la seguridad de que lo van a atender al momento que llegue, que no va a esperar, que su servicio está asegurado y puede planificar su tiempo. Por otro lado, la empresa también planifica mejor. Puede distribuir mejor su personal, su espacio, su logística, sus tiempos, haciéndose más eficiente. El objetivo principal de la tesis es diseñar un sistema electrónico que permita reservar las citas para atención en los talleres especializados de autos, específicamente en el taller Euroshop de Volkswagen. Y como objetivos específicos se tienen los siguientes: • Realizar un análisis del comportamiento de los clientes, sus motivaciones y necesidades en lo que a servicio de taller se refiere. • Se deberá estudiar la actual forma de operación del taller Euroshop y proponer un plan de acción con los cambios necesarios para obtener su operatividad. • Encontrar la manera de que el cliente y la empresa cambien su actual forma de operación y se orienten a un sistema de citas.

Exact time and location will be displayed from noon, Friday on the hotel lobby information terminals. The Society presently is informal—no officers or committees—and the only "official office holder" is L.E. Geisler, editor and publisher of the SEBHC JOURNAL. In the remote possibility that some SEBHC members want to establish a formal society, we advise them to send a proposed outline of same to the SEBHC JOURNAL. We will publish all those received before 5- Aug-87 in issue number 12 (August, 1987). The August JOURNAL issue will be available in the meeting room from about 13:00, Friday. Interested members can read what others have proposed in this issue, and may then discuss the proposals with other members also attending. If desired, they can draft a formal proposal for establishing a government, constitution and bylaws for the Society BEFORE meeting and acting on Lhe proposal. Note: This meeting will be quite brief, as most members are expecting to attend HUGCON-VI, and we don’t want them missing that. Subscribers visiting the meeting room may pick up their Aug-87 copy of the SEBHC JOURNAL there.

Основы операционной системы UNIX Copyleft (no c) - Fuck copyright! 1996-2004 В. Кравчук, OpenXS Initiative, идея, составление, перевод, примеры Введение Этот краткий (предположительно, 16 часов, из которых 6 - практические занятия) вводный курс предназначен для ознакомления с архитектурой, особенностями и основными средствами ОС UNIX. При успешном освоении, курс позволит свободно и продуктивно работать в ОС UNIX в качестве пользователя и продолжить изучение администрирования или программирования этой операционной системы. Изложение ведется, в основном, без привязки к особенностям какой-либо версии UNIX, но при необходимости конкретизации, она делается для систем SVR4, в частности, ОС Solaris 8. В последней версии (1.2, 11 марта 2004 года) обновлена хронология основных событий в истории ОС UNIX. История, версии и основные характеристики ОС UNIX История ОС UNIX началась в 1969 году в одном из подразделений AT&T Bell Laboratories, когда на "малоиспользуемой" машине DEC PDP-7 Кен Томпсон (Ken Thompson), Деннис Ричи (Dennis Ritchie) и другие (прежде занимавшиеся созданием ОС Multics) начали работу над операционной системой, названной ими первоначально Unics (UNiplexed Information and Computing System). В течение первых 10 лет развитие UNIX происходило, в основном, в Bell Labs. Соответствующие начальные версии назывались "Version n" (Vn) и предназначались для ЭВМ DEC PDP-11 (16-битовая) и VAX (32- битовая). Версии Vn разрабатывались группой Computer Research Group (CRG) в Bell Labs. Поддержкой занималась другая группа, Unix System Group (USG). Разработкой также занималась группа Programmer's WorkBench (PWB), привнесшая систему управления исходным кодом sccs, именованные каналы и ряд других идей.
