The boy was about fourteen. For a time he squatted, pushing the sand aside and trying to find the door. A few centimeters down, his hands met a gritty, solid material which, though neither concrete nor sandstone, shared the qualities of both sandfilled anic plastic. On it he scraped his fingers raw, but he could not locate the edges of the hatch. Then he stood and looked about him, his head moving continually as the heads of certain reptiles go back and forth, with no pauses at the terminations of the movements. He did this constantly, ceaselessly alwaysand for that reason it will not often be described again, just as it will not be mentioned that he breathed. He did。 with dilated eyes hypnotically dark he paused, his neck just w here the ant lion39。 I responded. She hesitated, then pushed the bushes farther apart. I saw a girl a little shorter than I was, and perhaps a little younger. She wore reddishbrown dungarees with a yellow shirt. T he cross stitched to the front of the dungarees was of a dar ker brown material. Her hair was tied on e ither side of her head with yellow ribbons. She stood still for a few seconds as though uncertain about leaving the security of the bushes, then curiosity got the better of her caution, and she stepped out. I stared at her because she was pletely a stranger. From time to time there were gatherings or parties w hich brought together all the children for miles around, so that it was astonishing to encounter one that I had never seen before. 畢業(yè)設(shè)計(jì)（論文） A grain of sand, teetering on the brink of the pit, trembled and fell in。 then a shaking of the top twigs in a bunch of bushes caught my eye. The branches parted, and a face looked out at me. It was a small face, sunburned, and clustered about by dark curls. The expression was somewhat serious, but the eyes sparkled. We regarded one another for a moment, then: 39。 Hullo!39。 other people, as far as she knew, did not have such pictures in their heads, either sleeping or wa king, so it would be unwise to mention them. That was good advice, and luc kily I had the sense to ta ke it. People in our district had a very sharp eye f or the odd, or the unusual, so that even my lefthandedness caused slight disap proval. So, at that time, and for some years afterwards, I did not mention it to anyone — indeed, I almost fot about it, for as I grew older the dream came less frequently, and then very rarely. But the advice stuc k. Without it I might have mentioned the curious understanding I had w ith my cousin Rosalind, and that would certainly have led us both into very grave trouble — if anyone had happened to believe me. Neither I nor she, I think, paid much attention to it at that time: we simply had the habit of caution. I certainly did not feel unusual. I was a normal little boy, growing up in a normal way, taking the ways of the world about me for granted. And I kept on like that unt il the day I met Sophie. Even then, the difference was not immediate. It is hindsight that enables me to fix that as the day when my first small doubts started to germinate. That day I had gone off by myself, as I often did. I was, I suppose, nearly ten y ears old. My next sister, Sarah, was five years older, and the gap meant that I played a great deal alone. I had made my way down the carttrack to the south, along the borders of several fields until I came to the high bank, and then along the top of the bank for quite a way. The bank was no puzzle to me then: it was far too big for me to think of as a thing that men could have built, nor had it ever occurred to me to connect it with the w ondrous doings of the Old People whom I sometimes heard about. It was simply the bank, ing round in a wide curve, and then running straight as an arrow towards the distant hills。 so it might be that w hat I was seeing was a bit of the world as it had been once upon a time — the w onderful world that the O ld People had lived in。 yet, waking, I had never seen the sea, or a boat. ... And the buildings were quite unlike any I knew. The traffic in the streets was strange, c arts running with no horses to pull them。蔣 老師不僅在學(xué)習(xí)上，對(duì)我嚴(yán)格要求，給予我悉心的指導(dǎo)，使我能夠不斷克服設(shè)計(jì)中遇到的困難 :而且在生活中也給予了我很多幫助。在此，我深表感謝 。 畢業(yè)設(shè)計(jì)（論文） 參考文獻(xiàn) [1] 梁海欣，江耀新，蔡若華﹒電子商務(wù)﹒北京：冶金工業(yè)出版社， 2020 年 1月 [2] 王學(xué)東﹒電子商務(wù)管理﹒重慶：重慶大學(xué)出版社， 2020 年 7 月 [3] 逯宇鐸，鄭曉明，錢(qián)永勝﹒電子商務(wù)實(shí)務(wù)﹒大連：大連理工大學(xué)出版社， 2020年 4 月 [4] 修文群，張蓬﹒ ERP/CRM/SCM/BI 協(xié)同商務(wù)建設(shè)指南﹒北京：科學(xué)出版社，2020 年 2 月 畢業(yè)設(shè)計(jì)（論文） 致 謝 詞 本論文的研究和撰寫(xiě)工作都是在我的指導(dǎo)老師張瑩的精心指導(dǎo)和悉心關(guān)懷下完成的。 企業(yè)通過(guò)導(dǎo)入 ERP 系統(tǒng)后，可幫助企業(yè)中的高階領(lǐng)導(dǎo)層參照 ERP 的管理理念，并結(jié)合企業(yè)實(shí)際對(duì)所有生產(chǎn)作業(yè)及管理業(yè)務(wù)的流程進(jìn)行分析、評(píng)價(jià)、改進(jìn)、優(yōu)化，使各業(yè)務(wù)過(guò)程占用資源最少、工作時(shí)間最短、程序更合理，效率最高。 ERP 是將企業(yè)所有資源進(jìn)行整合和集成管理，也就是說(shuō)將企業(yè)的三大流：物流，資金流，信息流進(jìn)行全面一體化管理的管理信息系統(tǒng)。它的主要特點(diǎn)是：以進(jìn)一步提高競(jìng)爭(zhēng)力，市場(chǎng)占有率和 獲取最大利潤(rùn)為目標(biāo)；以市場(chǎng)為導(dǎo)向，以客戶(hù)需求為中心；面向開(kāi)放、互動(dòng)的 SCM；實(shí)行協(xié)同商務(wù)、協(xié)同競(jìng)爭(zhēng)和雙贏原則；充分運(yùn)用先進(jìn)的管理技術(shù)、信息技術(shù)、網(wǎng)絡(luò)技術(shù)和集成技術(shù)。在 ERP 的實(shí)施過(guò)程中，面對(duì)部門(mén)的職責(zé)劃分、人為障礙等管理問(wèn)題，必須有足夠權(quán)威的領(lǐng)導(dǎo)作出有效的決策和強(qiáng)力的支持。同時(shí)， ERP 系統(tǒng)能全面提升企業(yè)的管理水平和市場(chǎng)競(jìng)爭(zhēng)力，但是其成功實(shí)施并不容易。投資者在對(duì)畢業(yè)設(shè)計(jì)（論文） 某個(gè)大型項(xiàng)目沒(méi)有全面了解之前，不可能作出投資決策或持續(xù)投資。 企業(yè)領(lǐng)導(dǎo)要對(duì) ERP 系統(tǒng)有較全面的了解，還要有實(shí)施 ERP 系統(tǒng)的信心和決心。沒(méi)有資深咨詢(xún)顧問(wèn)的正確指導(dǎo)， ERP 系統(tǒng)實(shí)施就難免多走彎路，甚至有可能成為失敗的案例。企業(yè)領(lǐng)導(dǎo)是投資 ERP 系統(tǒng)的決策者；項(xiàng)目經(jīng)理是實(shí)施 ERP 系統(tǒng)的組織者；實(shí)施人員是實(shí)施 ERP 系統(tǒng)的執(zhí)行者；具體業(yè)務(wù)人員是 ERP 系統(tǒng)中的操作者；咨詢(xún)顧問(wèn)是實(shí)施 ERP 系統(tǒng)的指導(dǎo)者。影響 ERP 系 統(tǒng)實(shí)施成功的因素主要有人、數(shù)據(jù)和技術(shù)，強(qiáng)有力的 IT 支持和保障是確保 ERP 系統(tǒng)長(zhǎng)期穩(wěn)定高效運(yùn)行的關(guān)鍵，而其核心卻是人。 人是 ERP 成功實(shí)施的核心 ERP 的實(shí)施對(duì)企業(yè)整合資源、提高管理具有重要的意義和價(jià)值，主要針對(duì)于企業(yè)的內(nèi)部管理，一方面是把企業(yè)所有的信息資源，即業(yè)務(wù)各個(gè)部分所涉及的資源緊密地結(jié)合起來(lái)，以達(dá)到資源利用的協(xié)調(diào)；另一方面是通過(guò)整合使得業(yè)務(wù)各環(huán)節(jié)資源的利用效率得到提高。同時(shí)，管理水平、競(jìng)爭(zhēng)優(yōu)勢(shì)等非量化效益也并不能直接反映為經(jīng)濟(jì)效益。 ERP 系統(tǒng)為決策者 提供了準(zhǔn)確而快捷的數(shù)字或圖表，讓決策者能夠準(zhǔn)確地了解企業(yè)的情 況。 ERP 的價(jià)值導(dǎo)向在于提高企業(yè)的工作效率，加強(qiáng)企業(yè)內(nèi)部資源的整合和協(xié)同，改變企業(yè)廣泛存在的信息孤島的局面，部分地提高企業(yè)經(jīng)濟(jì)效益，以及一定程度上管理的改進(jìn)。 ERP 系統(tǒng)是對(duì)企業(yè)物流、資金流、信息流進(jìn)行一體化管理的 軟件 系統(tǒng)，其核心
