Mayelana nalolu hlelo lokusebenza

Ukuze silingise, kufakwe idatha elandelayo:
- inombolo yeziteshi zesevisi;
- inani lamaklayenti azohlinzekwa;
- amathuba okusabalalisa amaklayenti ngezikhathi ezithile zokufika;
- ukusatshalaliswa okuhlukene kwezikhathi zesevisi kumakhasimende.

Ukusabalalisa okuhlukene kokufika nezikhawu zesevisi kungafakwa ngesandla noma kwenziwe kusetshenziswa okukodwa kokusabalalisa okulandelayo: okuchazile, okufanayo, ukusabalalisa kwe-Erlang, ukusatshalaliswa kwe-Weibull, okuvamile, nokuncishisiwe okuvamile.
Uma kukhiqizwa kulokhu kusatshalaliswa ngakunye, amapharamitha achazayo ayafakwa, isibonelo, ngokusabalalisa okuvamile yilawa: inani lesilinganiso, ukuhluka, kanye nenani lezikhawu. Ngesikhathi sokukhiqiza, isikhawu ngasinye, amathuba okufika kwamakhasimende kanye nesevisi ngokufanele kunqunywa ngokohlelo. Isamba senani lezikhawu sichaza isikhathi lapho amakhasimende afika futhi ahlinzekwa ngaso. Ngokushintsha amapharamitha, izimo ezahlukahlukene zingalingiswa. Inani lezikhawu zokusatshalaliswa kwamathuba amakhasimende afikayo kanye nenani lezikhawu zezikhathi zesevisi akudingekile ukuthi lifane.
Isevisi yamakhasimende isebenza ngomgomo othi First Come - First Served, kuye ngokuthi sikhona yini isiteshi esitholakalayo. Isicelo sikala amanani alandelayo: isilinganiso sesikhathi sokulinda samakhasimende emgqeni wesevisi; - isilinganiso sesikhathi sesevisi samakhasimende; - isikhathi esimaphakathi ohlelweni (ukulinda + isevisi); - ukusetshenziswa kweseva ngamaphesenti; - kanye ne-output (amakhasimende ngeyunithi ngayinye yesikhathi).
Idatha yezinhlelo ezilingisayo igcinwa kusizindalwazi se-SQLite esiqanjwe ngokuthi amasampula.db. Uhlu lwamasistimu asevele agciniwe luboniswa esikrinini esikhulu sohlelo lokusebenza, oluqanjwe ngokuthi AppMulti_Channel_Mass_Service, futhi ngokuchofoza into esohlwini, lukhethelwa umsebenzi owengeziwe.
Kusikrini esikhulu sohlelo lokusebenza, imisebenzi elandelayo iyatholakala: Isampula Entsha - ukufaka idatha yokulinganisa kwesistimu entsha; Hlela - ukulungisa nokusebenzisa uhlelo olukhethiwe; futhi Susa – ukususa uhlelo.
Ukwengeza ezintweni zemenyu esikrinini sasekhaya, le misebenzi elandelayo ifakiwe: Usizo; - Init DB ukulayisha kokuqala database; - Kopisha i-DB ekopisha isizindalwazi; - Gcina i-DB igcina i-database; - Izilungiselelo; - kanye nezixhumanisi kwezinye izinhlelo zokusebenza zombhali.
Ukufakwa kwedatha yesistimu entsha yokulingisa kanye nokuhlela nokusebenzisa isistimu ekhethiwe kwenziwa esibukweni esibizwa ngokuthi Umsebenzi Wesampula. Lapha ufaka: - igama lesistimu; - inani lamaseva; - inani lamaklayenti azolingisa kanye nakho kokubili ukusatshalaliswa okungenzeka (kwamakhasimende afikayo nanikezwa isevisi).
Kunezinkambu ezimbili zokubona ukusatshalaliswa ngeso lengqondo: Inani lefomethi ye-Interarrival PMF:prob,... kanye nesikhathi sesevisi inani lefomethi ye-PMF:prob,... Ukufakwa kwedatha ngokwako kwenziwa kumathebula ezingxoxo (Hlela; Ukufika Ngaphakathi kwe-PMF Hlela; kanye nesikhathi Sesevisi PMF) namakholomu amabili: isikhawu kanye namathuba ngalinye. Ngemva kokucindezela inkinobho ethi Londoloza, idatha efakiwe iboniswa kulezi zindawo ezishiwo ngenhla.
Kusukela Kumsebenzi Wesampula, imisebenzi yokukhiqiza ukusabalalisa okubili ifakwe nezinkinobho Khiqiza Okokufaka kanye Nokukhiqiza Isevisi, kanye nokwenza ukulingisa ngenkinobho ethi RUN SIMULATION.
Ngemva kokwenziwa kokulinganisa, umphumela uboniswa esikrinini Sokulingisa. Ukusuka lapho, umsebenzi wokuphrinta ungakhethwa ukulondoloza umphumela wokulingisa njengefayela le-.txt. Ukuphrinta kufaka phakathi umsebenzi Wokulondoloza Ifayela ngesakhiwo sesihlahla senkomba yefayela ledivayisi, futhi lapho ukhetha ifolda, kuvela inkinobho ethi Gcina, evumela ukulondoloza umphumela wokulingisa.

Ukukhiqizwa kokusatshalaliswa okubili kwenziwa yi-FlowActivity. Kusukela kuhlu olwehliswayo, uhlobo lokusabalalisa luyakhethwa, imingcele yayo yesici iyagcwaliswa, futhi ngenkinobho ethi Khiqiza, kuthebula lamakholomu amabili afanayo njengalapho kufakwa ukusabalalisa okusha, idatha yokusabalalisa ekhiqiziwe iyaboniswa.
