Athro Ymchwil Nodedig, Cadeirydd DSV
Trosolwyg
Rwy'n Athro Ymchwil Gwyddor Penderfyniadau ac yn dal Cadair DSV mewn Ymchwil Logisteg. Rwy'n sylfaenydd a Chyfarwyddwr Sefydliad Gweithgynhyrchu, Logisteg a Stocrestr PARC ar y cyd rhwng y Brifysgol a'r Diwydiant (sy'n cwmpasu RemakerSpace Prifysgol Caerdydd). Rwyf wedi sefydlu ac ar hyn o bryd yn gofalu am bartneriaeth strategol y Brifysgol â DSV. Cyn ymuno â Chaerdydd, roeddwn i'n gwasanaethu yng nghyfadran Prifysgol Salford (Canolfan Ymchwil Weithredol ac Ystadegau Cymhwysol), ac Ysgol Fusnes Copenhagen (Athro Otto Monsted, Adran Gweithrediadau).
Yng Nghaerdydd, rwy'n ymchwilio i ragfynegi a rheoli ansicrwydd ar gyfer gwella penderfyniadau stocrestr, gweithgynhyrchu, logisteg a chadwyn gyflenwi. Rwyf wedi cael y clod am uno'r disgyblaethau (seilos gynt) o ragweld ac optimeiddio stocrestr, ac rwy'n adnabyddus yn bennaf am y Syntetos-Boylan Approximation, dull rhagfynegi safonol, a'r dull Syntetos-Boylan-Croston o ddosbarthu rhagolygon. Mae fy llyfr 2021 gyda John Boylan wedi'i grynhoi yn y fideo hwn.
Mae fy ngwaith yn adlewyrchu cydweithio â mwy na 50 o brifysgolion a chwmnïau ledled y byd, ac mae wedi cael ei gefnogi gyda chyllid sy'n fwy na £5 miliwn (bron pob un ohonynt wedi'u sicrhau fel Prif Ymchwilydd ac mae bron pob un ohonynt wedi'u dyfarnu i'm Prifysgol gysylltiedig). Rwyf wedi cael fy nghyhoeddi mewn allfeydd academaidd blaenllaw (megis Decision Sciences, European Journal of Operational Research, Journal of Operations Management, a Production & Operations Management), ac mae gen i tua 13,500 o ddyfyniadau i'm gwaith.
Rwyf wedi cynghori llawer o sefydliadau ar faterion sy'n gysylltiedig â rhagfynegi stocrestr ac mae sawl dull/algorithm rydw i wedi'u cyd-ddatblygu yn cael eu defnyddio gan gorfforaethau meddalwedd mawr. Dros yr ychydig flynyddoedd diwethaf, rwyf wedi bod yn gweithio'n agos gyda: British Telecommunications (BT), Brother International, DSV, y grŵp Excelitas (Qioptiq), Ocado, a'r grŵp Ymateb Defnyddwyr Effeithlon (ECR) (yr wyf yn gweithio gyda manwerthwyr mwyaf Ewrop). Gellir dod o hyd i rai o'm heffaith ddiweddar yma.
Rwy'n Brif Olygydd yr IMA Journal of Management Mathematics (IMAMAN, Gwasg Prifysgol Rhydychen) ac yn Olygydd Cyswllt FORESIGHT, cyhoeddiad sy'n canolbwyntio ar ymarferwyr y Sefydliad Rhyngwladol Rhagolygon (IIF). Gwasanaethais fel Cyfarwyddwr yr IIF yn 2014 - 2022, ac ar hyn o bryd rwy'n gwasanaethu fel Is-lywydd y Gymdeithas Ryngwladol ar gyfer Ymchwil Stocrestrau (ISIR).
Ym Mhrifysgol Caerdydd, rwyf wedi derbyn gwobrau am ragoriaeth mewn addysgu ôl-raddedig, Gwobr Goruchwyliwr Doethurol Eithriadol Prifysgol Caerdydd 2016, a Gwobr Arloesedd ac Effaith Prifysgol Caerdydd mewn Busnes 2016 a 2019 am fy ngwaith gyda Panalpina World Transport Ltd. (DSV bellach) a Qioptiq Ltd., yn y drefn honno. Yn 2024 derbyniais (gyda Bahman Rostami-Tabar a Zied Babai) Fedal Goodeve gan y Gymdeithas Ymchwil Weithredol (ORS). Ac mae'n anrhydedd mawr i mi gael fy ethol yn 2026 yn un o Gymrodyr sefydlu'r Academi ar gyfer y Gwyddorau Mathemategol gan fy mod hefyd wedi derbyn Cwmnïaeth Ymchwil Weithredol gan yr ORS.

Ymchwil
Diddordebau ymchwil
Rwy'n gweithio ym maes Gwyddor Penderfyniadau, ac mae gen i ddiddordeb mewn datblygu algorithmau a modelau busnes stocrestr a / neu ragfynegi theoretically rigorous ond ymarferol hyfyw ac effeithiol.
Rwyf wedi gweithio, ac yn parhau i wneud hynny, ar ragfynegi stocrestr galw ysbeidiol. Mae'r gwaith hwn yn arbennig o berthnasol i gadwyni cyflenwi darnau sbâr (ac ar ôl gwerthu). Rwyf hefyd yn gweithio ar ragfynegi stocrestr yng nghyd-destun cadwyni cyflenwi dolen gaeedig (economi gylchol) a gweithgynhyrchu ychwanegion (3DP yn arbennig) cadwyni cyflenwi wedi'u galluogi. Mae fy ngwaith bob amser wedi cael ei danlinellu nid yn unig gan bryderon ariannol ond hefyd amgylcheddol, ac yn fwy diweddar cymdeithasol. Rwyf bob amser wedi bod yn ymwneud â lleihau darfodiad stocrestr, ac yn fwy diweddar, gyda chyfleoedd i atal darfodiad wedi'i gynllunio yn gyfan gwbl.
Mae fy niddordebau ymchwil presennol yn ymwneud â'r meysydd canlynol:
- Rhagolygon cadwyn gyflenwi ystadegol a beirniadol
- Stocrestr, ac anghywirdebau stocrestr, modelu mathemategol a rheoli
- Uno dadansoddol a chysyniadol o Stocrestr-Rhagfynegi
- Rhagfynegi Stocrestr yn: i) darnau sbâr, ii) ar ôl gwerthu, iii) manwerthu, iv) dolen agos, v) cadwyni cyflenwi wedi'u galluogi gan 3DP
- Rhestr (a/neu) Rhagfynegi ar gyfer cynaliadwyedd amgylcheddol: lleihau neu ddileu darfodiad
- Rhestr (a/neu) Rhagolygon er lles cymdeithasol

Addysgu
Addysgu - Prifysgol Caerdydd
Mae fy amser yn cael ei neilltuo 100% i ymchwil (a throsglwyddo gwybodaeth).
Yn flaenorol, yn Ysgol Busnes Caerdydd, bûm yn dysgu Modelu Logisteg, Dadansoddi Gweithrediadau a Rheoli Gweithrediadau yn rhaglenni MSc yr Adran Rheoli Logisteg a Gweithrediadau (LOM). Rwyf wedi cyfrannu'n sylweddol at ddatblygu'r cwricwlwm (e.e. modiwl Dadansoddi Gweithrediadau) ac wedi derbyn gwobrau am ragoriaeth mewn addysgu ôl-raddedig.
Addysgu - Yn rhyngwladol
Yn ogystal â'r DU, rydw i wedi dysgu'n rhyngwladol yn Tsieina, Colombia, Denmarc, Ffrainc, Gwlad Groeg, yr Eidal a Latfia. Roedd yr holl gyrsiau ym meysydd Rheoli Gweithrediadau, Ymchwil Weithredol (Gwyddoniaeth Rheoli) ac Ystadegau Cymhwysol.
